DESCRIPTION

The RC5000 serves many performance critical embedded

applications, such as high-end internetworking systems, color

printers, and graphics terminals.

The RC5000 is optimized for high-performance applications,

with special emphasis on system bandwidth and floating point

operations, through integration of high-performance computational

units and a high-performance memory hierarchy. For this class of

application, the result is a relatively low-cost CPU capable of

approximately 400 Dhrystone MIPS.

IDT’s objectives in offering the RC5000 include:

◆Offering a high performance upgrade path to existing

embedded customers in the internetworking, office auto-

mation and visualization markets.

◆Providing a significant improvement in the floating- point

performance currently available in a moderately priced

MIPS CPU.

◆Providing improvements in the memory hierarchy of desk-

top systems by using large primary caches and integrat-

ing a secondary cache controller.

◆Enabling improvements in performance through the use of

the MIPS-IV ISA.

Instruction issue mechanism

The RC5000 recognizes two general classes of instructions for

multi-issue:

◆Floating-point ALU

◆All others

These instruction classes are pre-decoded by the RC5000, as

they are brought on-chip. The pre-decoded information is stored in

the instruction cache.

Assuming that there are no pending resource conflicts, the

RC5000 can issue one instruction per class per pipeline clock

cycle. Note that this broad separation of classes insures that there

are no data dependencies to restrict multi-issue.

However, long-latency resources in either the floating-point ALU

(e.g. DIV or SQRT instructions) or instructions in the integer unit

(such as multiply) can restrict the issue of instructions. Note that

the R5000 does not perform out-of-order or speculative execution;

instead, the pipeline slips until the required resource becomes

available.

There are no alignment restrictions on dual-issue instruction

pairs. The RC5000 fetches two instructions from the cache per

cycle. Thus, for optimal performance, compilers should attempt to

align branch targets to allow dual-issue on the first target cycle,

since the instruction cache only performs aligned fetches.

Instruction set architecture

The RC5000 implements the MIPS-IV 64-bit ISA, including CP1

and CP1X functional units (and their instruction set).

Integer pipeline

The RC5000 is a limited dual-issue machine that utilizes a tradi-

tional 5-stage integer pipeline. This basic integer pipeline of the

RC5000 is illustrated in Figure 1. The integer instruction execution

speed is tabulated (in number of pipeline clocks) as follows:

The RC5000’s short pipeline keeps the load and branch latencies

very low. The caches contain special logic that allows any combina-

tion of loads and stores to execute in back-to-back cycles without

requiring pipeline slips or stalls. (This assumes that the operation

does not miss in the cache.)

RC5000 Computational Units

The RC5000 contains the following computational units:

Integer ALU. The RC5000 implements a full, single-cycle 64-bit

ALU for all integer ALU functions other than multiply and divide.

Bypassing is used to support back-to-back ALU operations at the

full pipeline rate, without requiring stalls for data dependencies.

Integer Multiply/Divide Unit. This unit is separated from the

primary ALU, to allow these longer latency operations to run in

parallel with other operations. The pipeline stalls only if an attempt

to access the HI or LO registers is made before the operation

completes.

Floating-point ALU. This unit is responsible for all CP1/CP1X

ALU operations other than DIV/SQRT. The unit is pipelined to allow

a single-cycle repeat rate for single-precision operations

Floating-point DIV/SQRT unit. This unit is separated from the

other floating-point ALU, so that these long latency operations do

not prevent the issue of other floating point operations.

In addition, the RC5000 implements separate logical units to

implement loads, stores, and branches.

Operating frequency

The input clock operates in a frequency range of 33MHz to

100MHz. The pipeline frequency for the RC5000 is 2 to 8 times the

input clock (up to the maximum for the speed grade of CPU).

Thermal considerations

The RC5000 utilizes special packaging techniques, to improve

the thermal properties of high-speed processors. The RC5000 is

packaged using cavity down packaging in a 223-pin PGA package

with integral thermal slug, and a 272-pin BGA package. These

packages effectively dissipate the power of the CPU, increasing

device reliability.

The RC5000 utilizes an all-aluminum package with the die

attached to a normal copper lead frame mounted to the aluminum

casing. Due to the heat-spreading effect of the aluminum, the

package allows for an efficient thermal transfer between the die

and the case. The aluminum offers less internal resistance from

one end of the package to the other, reducing the temperature

gradient across the package and therefore presenting a greater

area for convection and conduction to the PCB for a given temper-

ature. Even nominal amounts of airflow will dramatically reduce the

junction temperature of the die, resulting in cooler operation.

The RC5000 is guaranteed in a case temperature range of 0° to

+85° C. The type of package, speed (power) of the device, and

airflow conditions affect the equivalent ambient temperature condi-

tions that will meet this specification.

The equivalent allowable ambient temperature, TA, can be

calculated using the thermal resistance from case to ambient

(∅CA) of the given package.

The following equation relates ambient and case temperatures:

TA = TC - P * ∅CA

where P is the maximum power consumption at hot temperature,

calculated by using the maximum ICC specification for the device.

Typical values for ∅CA at various airflows are shown in Table 1.

Table 2: Thermal Resistance (∅∅CA) at Various Airflows

Note: The RC5000 implements advanced power management to

substantially reduce the average power dissipation of the device. This

operation is described in the IDT79RV5000 RISC Microprocessor

Reference Manual.

Note:

Per the RC5000 Documentation errata, Revicion 1.0, dated

February 1999 and per the RC5000 Device errata, dated February

1999, mode bits 20, 33 and 37 must be set to 1.
