CPU Execution Core
found in the award-winning RC32364 microprocessor. The RISCore
32300 implements the Enhanced MIPS-II ISA. Thus, it is upwardly
compatible with applications written for a wide variety of MIPS architec-
ture processors, and it is kernel compatible with the modern operating
systems that support IDT’s 64-bit RISController product family. The
RISCore 32300 was explicitly defined and designed for integrated
processor products such as the RC32332. Key attributes of the execu-
tion core found within this product include:
The RC32332 integrates the RISCore 32300, the same CPU core

– 3.3V core supply is 5V I/O tolerant
3.3V or 2.5V core supply with 3.3V I/O supply
EJTAG in-circuit emulator interface
High-speed, 5-stage scalar pipeline executes to 150MHz. This
high performance enables the RC32332 to perform a variety of
performance intensive tasks, such as routing, DSP algorithms,
etc.
32-bit architecture with enhancements of key capabilities. Thus,
the RC32332 can execute existing 32-bit programs, while
enabling designers to take advantage of recent advances in
CPU architecture.
Count leading-zeroes/ones. These instructions are common to a
wide variety of tasks, including modem emulation, voice over IP
compression and decompression, etc.
Cache PREFetch instruction support, including a specialized
form intended to help memory coherency. System programmers
can allocate and stage the use of memory bandwidth to achieve
maximum performance.
