DescriptionIDT RV4700 64-Bit RISC Microprocessor
OverviewThe 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
