Description
The IDT79R4700 64-bit RISC Microprocessor is both software and
pin-compatible with the R4
XXX
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.
