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
