SH775x (SH-4) Series
SuperH(R) RISC Processor
Description
T
he SH775x (SH-4) series is a high-performance, well integrated, cost-effective, 2-issue superscalar RISC microprocessor for embedded applications. The SH775x series delivers best-in-class performance, on-chip integration and code size, with excellent low power consumption, support tools and chipsets from Hitachi and third party vendors, as well as a migration path to higher performance and lower power. This complete package makes the SH775x series the optimal choice for use in data processing, communications, industrial, transportation and high-end consumer applications.
