Description
The IDT79R4700 64-bit RISC Microprocessor is both software and
pin-compatible with the R4XXX processor family. With 64-bit processing
capabilities, the R4700 provides more computational power and data
movement bandwidth than is delivered to typical embedded systems by
32-bit processors.
The R4700 is upwardly software compatible with the IDT79R3000
microprocessor family, including the IDTRISController 79R3051,
R3052, R3041, R3081 as well as the R4640, R4650, RC64474/
475 and R5000. An array of development tools facilitates rapid
development of R4700-based systems, allowing a variety of customers
access to the MIPS Open Architecture philosophy.
