Device Overview1
Extending Integrated Device Technology’s (IDT) RISCore4000 based
choices (see Table 1), the RC64474 and RC64475 are high perfor-
mance 64-bit microprocessors targeted towards applications that require
high bandwidth, real-time response and rapid data processing and are
ideal for products ranging from internetworking equipment (switches,
routers) to multimedia systems such as web browsers, set-top boxes,
video games, and WindowsCE based products. These processors are
rated at 330 Dhrystone MIPS and 125 Million floating point operations
per second, at 250 MHz. The internal cache bandwidth for these devices
is over 3GB/second. The 64-bit external bus bandwidth is at more than
1000MB/s, and the 32-bit external bus bandwidth is at 500MB/s.
The RC64474 is packaged in a 128-pin QFP footprint package and
uses a 32-bit external bus, offering the ideal combination of 64-bit
processing power and 32-bit low-cost memory systems. The RC64475
is packaged in a 208-pin QFP footprint package and uses the full 64-bit
external bus. The RC64475 is ideal for applications requiring 64-bit
performance and 64-bit external bandwidth.
IDT’s RISCore4000 is a 250MHz 64-bit execution core that uses a
5-stage pipeline, eliminating the “issue restrictions” associated with
other more complex pipelines.
The RISCore4000 implements the
MIPS-III Instruction Set Architecture (ISA) and is upwardly compatible
with applications that run on earlier generation parts.
Implementation of the MIPS-III architecture results in 64-bit opera-
tions, improved performance for commonly used code sequences in
1. Detailed system operation information is provided in the RC64474/RC64475
user’s manual.
operating system kernels, and faster execution of floating-point intensive
applications.
The RISCore4000 integer unit implements a load/store architecture
with single cycle ALU operations (logical, shift, add, subtract) and an
autonomous multiply/divide unit. The ALU consists of the integer adder
and logic unit. The adder performs address calculations in addition to
arithmetic operations, and the logic unit performs all of the processor’s
logical and shift operations. Each unit is highly optimized and can
perform an operation in a single pipeline cycle. Both 32- and 64-bit data
operations are performed by the RISCore4000, utilizing 32 general
purpose 64-bit registers (GPR) that are used for integer operations and
address calculation. A complete on-chip floating-point co-processor
(CP1), which includes a floating-point register file and execution units,
forms a “seamless” interface, decoding and executing instructions in
parallel with the integer unit.
CP1’s floating-point execution units support both single and
double precision arithmetic—as specified in the IEEE Standard 754—
and are separated into a multiply unit and a combined add/convert/
divide/square root unit. Overlap of multiplies and add/subtract is
supported, and the multiplier is partially pipelined, allowing the initiation
of a new multiply instruction every fourth pipeline cycle.
The floating-point register file is made up of thirty-two 64-bit regis-
ters. The floating-point unit can take advantage of the 64-bit wide data
cache and issue a co-processor load or store doubleword instruction in
every cycle. The RISCore4000’s system control coprocessor (CP0)
registers are also incorporated on-chip and provide the path through
which the virtual memory system’s page mapping is examined and
changed, exceptions are handled, and any operating mode selections
are controlled.
