2D FIR Filter IP Core
Overview
The 2D FIR Filter IP core performs real-time 2D convolution of windowed portions
of incoming video frames with coefficient matrices held in internal memory. Its
flexible architecture supports a wide variety of filtering operations on various Lattice
device families. The highly parameterized design takes advantage of the embed ded DSP blocks available in Latti c e FPGAs.
A simple I/O handshake makes the core suitable for either streaming or bursty input video data. Coefficients may be set at
compile time, or updated in system via a simple memory interface.
Features
Single color plane
Single-rate, interpolating, and decimating filter configurations
Input frame size set at compile-time
Static or dynamic zoom and pan
User-specified 2D convolution kernel
Separable and non-separable kernel support
Kernel symmetry optimization
Updatable coefficient
