(IDT) RISController 79RC32364 of Embedded Microprocessors.
The 79RC32364 brings 64-bit performance levels to lower cost systems. High performance is achieved through the use of advanced techniques such as large on-chip two-way set-associative caches, a streamlined high-speed pipeline, high-bandwidth, and facilities such as early restart for data cache misses. Also, through IDT proprietary enhancements to the base MIPS architecture, the processor's performance, in particular applications, is further extended.
The 79RC32364 is the first member of a new processor family that uses IDT's proprietary RISCore32300 CPU core. The RISCore32300 core continues IDT's tradition of high-performance through high-speed pipelines, high-bandwidth caches, and architectural extensions that serve the needs of specific markets; yet the RC32364 provides these capabilities in a low-cost, high-speed 32-bit enhanced MIPS architecture core, enabling a new level of price performance.
Around the RISCore32300, the 79RC32364 integrates a fully RC5000 compatible memory management unit (MMU), substantial amounts of efficient cache memory, an enhanced debug capability, digital signal processing (DSP) extensions, and a low-cost system interface. The resulting device is well suited to the needs of mid-range communications equipment, xDSL equipment, and consumer devices.
Also, being upwardly software compatible with the RC3000 family, the 79RC32364 will serve in many of the same applications as well as support applications that require integer DSP functions.
