One field is transmitted at a time and thus uses only half the bandwidth. Most modern displays support progressive scan, and to display interlaced video on progressive scan displays, deinterlacing, a method of combining the two fields into a frame, is applied to the video signal. Because each frame of interlaced video is composed of two fields that are captured at different moments in time, there will be flickers and jagged edges in the combined frame. A good deinterlacing algorithm should reduce these artifacts as much as possible and yield a good video quality in the process. The Deinterlacer IP core provides several deinterlacing algorithms for different video quality and resource requirements: weave, bob, intra and inter motion adaptive deinterlacing algorithms. Block Diagram Figure 2-1. Deinterlacer IP Core Block Diagram Deinterlacer IP Core Frame Buffer Pixels In Write FIFO Read FIFO Line Buffer Deinterlacing Engine Pixels Out Memory Interface Memory Controller Figure 2-1 shows the block diagram of the Deinterlacer IP core. The core consists of three modules: frame buffer, line buffer and deinterlacer engine. The frame buffer module manages memory write/read and combines interlaced fields into progressive frames. The line buffer module and deinterlacing engine process the combined frames to reduce artifacts. In the deinterlacer, several clock sources are involved. When frame rate conversion is enabled, there are two clocks in the video data path: input pixel sample clock and output pixel sample clock. The frame buffer module handles the rate conversion, and the line buffer and deinterlacing engine operate at the output pixel clock rate. When frame rate conversion is disabled, all the modules in the video data path operate at input pixel clock rate. When dynamic parameter updating is selected, the parameter bus can be configured to run on a separate clock. By default, the parameter bus runs on the input pixel sample clock. The memory interface always operates on a separate clock. The input data must be in interlaced video format. An interlaced frame is composed of two fields. The first field in the interlaced frames can be configured to be the top field or the bottom field. This parameter can be configured at run time. When processing YCbCr 4:2:2 video format, the core copies neighboring pixels' Cb and Cr vectors to construct the YCbCr 4:4:4 format for deinterlacing. The Deinterlacer IP core does not use multipliers. (c) 2013 Lattice Semiconductor Corp.

IPUG97_01.1, September 2013 6 Deinterlacer IP Core User's Guide Functional Description Deinterlacing Algorithms The Deinterlacer IP core supports weave, bob, intra and inter motion adaptive deinterlacing algorithms. Weave The weave algorithm simply combines the two interlaced fields together. There is no line buffer module or deinterlacing engine instantiated in the core. Weaving is fine when there is no change in the image between fields, but any change will result in artifacts known as "combing," when pixels in one frame do not line up with pixels in the others, forming jagged edges. Bob The bob algorithm uses one single field to generate a frame by averaging up lines and down lines to generate new lines. Either even or odd fields can be selected for progressive frame generation. Intra Motion Adaptive Deinterlacing Figure 2-2. Intra Deinterlacing Engine Structure Current Frame Spatial Predictor Motion Adaptive Filter Output Frame Intra Deinterlacing Engine Figure 2-2 shows the structure of the intra deinterlacing engine. The intra motion adaptive deinterlacing algorithm enhances the quality of the combined frames by using a spatial predictor with advanced ELA (Edge-based Line Average) algorithm to predict the center pixel. The intra Motion Adaptive Filter uses an enhanced multi-stage median filter with robustness control to perform motion adaptive deinterlacing. Inter Motion Adaptive Deinterlacing Figure 2-3 shows the structure of the inter motion deinterlacing engine. The inter motion adaptive deinterlacing algorithm uses two combined frames (four fields) to generate one progressive frame. The motion detector uses a 3x3 pixel window SAD (Sum of Absolute Differences) algorithm to determine the motion of the center pixel. The SAD value is divided by two thresholds (TH1 and TH2) into three pixel motion regions: still pixel, slow motion pixel or fast motion pixel. Each region has a separate filter with robustness control to generate the output pixel. The final output pixel value is determined by the detector value and the threshold values. The two threshold values can be updated at run time. IPUG97_01.1, September 2013 7 Deinterlacer IP Core User's Guide Functional Description Figure 2-3. Inter Deinterlacing Engine Structure Current Frame Spatial Predictor Fast Motion Filter MUX Slow Motion Filter Output Frame Still Pixel Filter Motion Detector (SAD) Previous Frame Inter Deinterlacing Engine Frame Rate Conversion The Deinterlacer IP core provides a simple frame rate conversion by copying or dropping frames. When frame rate conversion is enabled, the core's output data path runs at the output pixel clock rate, and the core needs one more external frame memory space. The output frame rate is controlled by the output pixel sample clock and dout_enable signal. When dout_enable signal is high, the core outputs pixels continuously. When there is no new interlaced video frame, the core will output the last progressive frame repeatedly. When frame rate conversion is disabled, the core's output data path will run on the input pixel sample clock. The output frame is generated directly from the input interlaced video stream. If there is no new input video frame, the core will stop outputting data. Dynamic Parameters Updating The Deinterlacer IP core provides a parameter bus port for internal parameter update at run time. The parameters are double-buffered so that the core's operation is not impacted when they are changed. The new values are buffered and transferred to the working registers when the core is ready to accept a new configuration. The UPDATE register is used to indicate when the new values are consumed and when the buffers can accept new data. The parameter register maps are included in Table 2-1. Table 2-1. Parameter Register Maps Address 0x00 Register FRMWIDTH Size Read/Write Description 32 Frame width register. The FRMWIDTH value must be (frame width - 1). The minimum value is 63, and the maximum value is the maximum frame Read/Write width specified on the IP GUI minus 1. The default value is the maximum value. Frame width must be an even number (i.e. FRMWIDTH must be odd). 0x04 FRMHEIGHT 32 Frame height register. The FRMHEIGHT must be (frame height - 1). The minimum value is 63, and the maximum value is the maximum frame Read/Write height specified on the IP GUI minus 1. The default value is the maximum value. Frame height must be an even number (i.e. FRMHEIGHT must be odd). 0x08 INITFLD 32 First field register. Specifies the first field in the interlaced input frames. Read/Write 0 for top field and 1 for bottom field. The default value is the corresponding parameter specified on the IP GUI. 0x0C BYPASS 32 BYPASS mode register. The value can be 0 or 1. When the BYPASS Read/Write register is 1, the Deinterlacer IP core passes the interlaced video through unaltered. The default value is 0. IPUG97_01.1, September 2013 8 Deinterlacer IP Core User's Guide Functional Description Address Register Size Read/Write Description 0x10 KEEP 32 KEEP mode register. The value can be 0 or 1. When the KEEP register is 1, the core will be locked. The core outputs the same frame repeatedly Read/Write if frame rate conversion is active; otherwise it generates no output frames. The default value is 0. 0x14 INTER_TH1 32 SAD threshold for still pixel for the inter algorithm. The maximum Read/Write value is 65535. N/A for other algorithms. The default value is the corresponding parameter specified on the IP GUI. 0x18 INTER_TH2 32 SAD threshold for slow motion pixel for inter algorithm. The maximum value is 65535. N/A for other algorithms. The default value is the Read/Write corresponding parameter specified on the IP GUI. The INTER_TH2 must be greater than INTER_TH1 value. 0x1C UPDATE 32 Update parameters enable register. The value can be 0 or 1. Setting Read/Write this bit to 1 triggers the update of parameters. The core resets it to 0 after the parameters have been updated. The default value is 0. All the parameter registers can be written to only when the UPDATE register bit is 0. The parameters KEEP, INTER_TH1 and INTER_TH2 will take effect at the next frame, regardless of the UPDATE value. When the UPDATE bit is set to 1, the parameters FRMWIDTH, FRMHEIGHT, INTIFLD and BYPASS will take effect when the frmsync_in signal is active, indicating a new input frame is arriving. After updating its internal parameters, the core resets the UPDATE bit to indicate that the parameter registers are now empty and can take on new values. Memory Bandwidth and Size The Deinterlacer IP core stores and retrieves pixels to/from external memory using memory burst write and read commands. When DDR2 is used for external memory, one burst operation, (burst_length*burst_count/2)*memory_data_width bit, cannot exceed the size of a single video line. A single video line will be transferred though multiple burst write/read transactions internally. For weave, bob and intra algorithms, the Deinterlacer IP core needs a 2-frame memory storage space; if frame rate conversion is active, a 3-frame storage space is required. When the output frame rate is the same as the input frame rate, the required memory bandwidth is twice the input data rate. When the output frame rate is double the input frame rate, the required memory bandwidth is triple the input data rate. For the inter algorithm, the Deinterlacer IP core uses two interlaced frames to generate one progressive frame; it needs a 3-frame storage space. If frame rate conversion is enabled, the core needs a 4-frame memory space. When the output frame rate is the same as the input frame rate, the required memory bandwidth is triple the input data rate. When the output frame rate is double the input frame rate, the required memory bandwidth is five times the data rate of the input video stream. For example, for 8-bit YCbCr 4:2:2 pixel, parallel deinterlacing, if the input pixel sample clock is 74.25MHz and output pixel sample clock is 148.5MHz, the required bandwidth for the intra algorithm is 2*8*(74.25+148.5) = 3564 bit*MHz. The required bandwidth for the inter algorithm is 2*8*(74.25+2*148.5) = 5940 bit*MHz. If the memory data with is 32, the require memory clock will be (3564/32) = 111.375 MHz for the intra algorithm and (5940/32) = 185.625MHz for the inter algorithms. The total external memory size the core requires can be viewed on the Deinterlacer IP GUI.

The core asserts its ready output when it is ready to receive data. When the driving module has data to pass to the deinterlacer, it asserts the core's dvalid_in port and at the same time places the input video data on the din port. The frmsync_in input should be driven to a `1' during the clock cycle when the very first pixel of the interlaced frame is active. Similarly, dvalid_out is active when valid output pixel data is available on dout, and frmsync_out marks the first pixel in the output progressive frames. The ports fwidth_out and fheight_out indicate the current output frame's width and height, respectively, These are valid only when frmsync_out is asserted. When the input signal dout_enable is asserted, the core will output progressive video pixels. When dout_enable is de-asserted, the core stops generating output pixels after some delay, which is less than 16 output pixel sample clock cycles. Memory Interface The Deinterlacer IP core implements a flexible memory interface which operates on a separate clock from the main core. When connecting to DDR2 memory controller, the burst length and burst count of deinterlacer should have the same values as those of DDR2 memory controller; when connecting to DDR3 memory controller, the burst length of deinterlacer should have the same value with DDR3 memory controller, while the burst count of deinterlacer should be half as that of DDR3 memory controller. The deinterlacer assumes a memory byte addressing scheme. When connecting the memory controller, the address connection should be adjusted according to the DDR memory data width. Normally the address connection can be (Assuming the DDR2/3 memory has 27 bits address width): ddr_addr = {1'b0,mem_addr[25:0]}; // for 8-bit DDR memory only ddr_addr = {2'b00,mem_addr[25:1]}; // for 16-bit DDR memory only ddr_addr = {3'b000,mem_addr[25:2]}; // for 32-bit DDR memory only And the corresponding command should be: ddr_cmd ddr_cmd_valid = (write_cmd) ? 4'b0010 : 4'b0001; // (write_cmd) ? WRITE : READ = (write_cmd || read_cmd); IPUG97_01.1, September 2013 11 Deinterlacer IP Core User's Guide Functional Description To get maximum throughput on the memory bus (about 5% increase compared to normal connection), the user needs to steer clear of write-to-precharge/read-to-precharge/precharge-to-active during row switching. That is, to access each bank in turn by using write/read with auto-precharge command to close current bank immediately after current burst write/read. In order to adopt this policy, the users should fine tune the combination of Row/Bank/Column address to get the best throughput. For example, when DDR2 memory data width is 16, row size is 14, column size is 10, bank size is 8, burst length is 8 and burst count is 1, which means memory controller user interface data width is 32, row address is 14 bits, column address is 10 bits, bank address is log2(bank size)=3 bits and log2(burst length * burst count)= 3 bits. The memory controller address mapping inside the memory controller IP core is ddr_addr = {row_addr[13:0], bank_addr[2:0], col_addr[9:0]} In order to get the best throughput, we increase the col_addr[2:0] first to utilize the burst operation, then we increase the bank_addr[2:0], followed by increasing the rest of col_addr[9:3], and finally with the row_addr. So the interface to the DDR2/3 memory will look like: ddr_addr = {2'b00, mem_addr[25:14], mem_addr[6:4], mem_addr[13:7], mem_addr[3:1]}; The corresponding command should be: ddr_cmd = (write_cmd) ? 4'b0100 : 4'b0011; // (write_cmd) ? WRITEA : READA As the memory controller user interface data width is 32, mem_addr[1:0] will always be zero. The core has internal control logic to arbitrate between memory write and read operations, ensuring the write_cmd and read_cmd are not asserted at the same time. Two clock cycles after the write_data_ready is asserted, data will be available on the write_data port. That means the parameter "Data_rdy to Write Data Delay" of memory controller must be set to 2 The cmd_ready can be asserted once every two clock cycles, and it should have at least a one-cycle interval, which is consistent with Lattice DDR Memory Controller IP cores. Parameter Register Read/Write Interface The Deinterlacer IP core implements a simple register read/write interface for run-time parameter updates. The parameter bus interface can be configured to run on a separate clock. It operates at the input pixel clock rate by default. When pwrite is high, pwdat and paddr must contain valid data. The contents of all parameter registers will be transferred to the core's internal storage when UPDATE is asserted. If a parameter hadn't been written to before the assertion of UPDATE, its old value will be transferred into the internal storage. prdat contains register read data corresponding to the address value placed on the paddr in the previous clock cycle. When the parameter bus data width is equal to 32, paddr[1:0] should be fixed to 0. When the parameter bus data width equals 16, paddr[0] should be fixed to 0. The parameter bus data width should be configured based on the system CPU's data width. IPUG97_01.1, September 2013 12 Deinterlacer IP Core User's Guide Functional Description Timing Specifications Video Input/Output Timing The Deinterlacer IP core supports single-color, YCbCr 4:2:2, YCbCr 4:4:4 or RGB video format. For YCbCr 4:4:4 or RGB video format, the three planes are interleaved for serial deinterlacing and combined on the din and dout ports for parallel deinterlacing. Figures 2-5 and 2-6 show the timing of RGB serial deinterlacing and parallel deinterlacing. Figure 2-5. RGB Serial Deinterlacing iclk ready dvalid_in frmsync_in din R G B R G B ... ... ...

For YCbCr 4:2:2 video serial deinterlacing, the input and output sequence should be Cb, Y, Cr, Y, .... For parallel deinterlacing, the Y plane occupies the upper bits of the din and dout ports, and the Cb and Cr planes the lower bits. Cb and Cr planes are interleaved in the lower half, and Cb comes before Cr. Figures 2-7 and 2-8 show the timing of YCbCr 4:2:2 serial deinterlacing and parallel deinterlacing.

When the dout_enable is de-asserted, the core will stop outputting data after a certain delay. Similarly, when the dout_enable is asserted, the core will begin outputting data after a certain delay. The number of delay clocks is different for different deinterlacing algorithms and the maximum value is less than 16 clocks. The asserting and de-asserting of dout_enable can be used to generate horizontal blanks and vertical blanks depending on the output video format.

Deinterlacer IP Core User's Guide Functional Description Video Frame Timing Figure 2-10 shows the frame timing when frame rate conversion is disabled. After accepting one input interlaced frame, the core starts generating progressive frames. The output frame is driven by the input frame. When a new input frame arrives before the current output frame is finished, the current output frame is dropped, and a new output frame is started. After the last input frame, the deinterlacer stops generating output frames. Figure 2-10.

Output frames run on a separate output pixel clock. The output frame rate is determined by the output pixel clock and dout_enable signal. The core generates output frames based on the oldest pending input frame(s). When a new input frame is received, the core pushes out the oldest frame and exports the second oldest frame. When there is no new frame input, the core exports the stored frames and then keeps exporting the last frame repeatedly. When the external memory is fully occupied by the unconsumed frames (no more space for new frames), the core will overwrite the latest input frame. Figure 2-11.

FW and FH are the video frame width and height. IFLD is the INITFLD register value, BP is the BYPASS register value and KP is the KEEP register value. The parameter bus can be configured to operate on a separate clock. By default, it operates at input pixel clock rate. The parameter registers are writable only when the UPDATE register is 0. When the UPDATE register bit is set to 1, the core will update its internal parameter registers with the new values at the next active frmsync_in and reset the UPDATE register bit. Figure 2-14.

IPUG97_01.1, September 2013 21 Deinterlacer IP Core User's Guide Chapter 4: IP Core Generation and Evaluation This section provides information on how to generate the Deinterlacer IP core using the Diamond or ispLEVER IPexpress tool, and how to include the core in a top-level design. Licensing the IP Core An IP core- and device-specific license is required to enable full, unrestricted use of the Deinterlacer IP core in a complete, top-level design. Instructions on how to obtain licenses for Lattice IP cores are provided on the IP Core Purchasing and Licensing Process page of the Lattice web site. Users may download and generate the Deinterlacer IP core and fully evaluate the core through functional simulation and implementation (synthesis, map, place and route) without an IP license. The Deinterlacer IP core supports Lattice's IP hardware evaluation capability, which makes it possible to create versions of the IP core that operate in hardware for a limited time (approximately four hours) without requiring an IP license. See "Hardware Evaluation" on page 27 for further details. However, a license is required to enable timing simulation, to open the design in the Diamond or the ispLEVER EPIC tool, and to generate bitstreams that do not include the hardware evaluation timeout limitation. Getting Started The Deinterlacer IP core is available for download from the Lattice IP server using the IPexpress tool. The IP files are automatically installed using ispUPDATE technology in any user-specified directory. After the IP core has been installed, the IP core will be available in the IPexpress GUI dialog box shown in Figure 4-1. To generate a specific IP core configuration, the user specifies: * Project Path - Path to the directory where the generated IP files will be located * File Name - "username" designation given to the generated IP core and corresponding folders and files * (Diamond) Module Output - Verilog or VHDL * (ispLEVER) Design Entry Type - Verilog HDL or VHDL * Device Family - Device family to which the IP core is to be targeted (e.g. LatticeECP2M, LatticeECP3, etc.). Only families that support the particular IP core are listed. * Part Name - Specific targeted part within the selected device family Configuring the Deinterlacer IP Core in IPexpress The Deinterlacer configuration GUI is accessed via the IPexpress tool, and provides an interface for setting the desired parameters and invoking the IP core generator. The start-up IPexpress page allows the user to select the IP to be generated, project directory, user-designated module name, design entry type, and target device. The "File Name" will be used as the username in the core generation. The Deinterlacer IP core is found under IP > DSP, as shown below. (c) 2013 Lattice Semiconductor Corp.
