IDT79RC4640™ Low-Cost Embedded 64-bit RISController w/ DSP Capability
●The IDT79RC4640 is a low-cost member of the Integrated Device Technology, Inc. RC4000 family, targeted to a variety of performance-hungry embedded applications. The RC4640 continues the RC4000 tradition of high-performance through high-speed pipelines, high-band-width caches and bus interface, 64-bit architecture, and careful attention to efficient control. The cost of this performance is reduced by removing functional units frequently not required for many embedded applications.
●The RC4640 supports a wide variety of embedded processor-based applications, such as internetworking equipment (routers, switches), office automation equipment (printers, scanners), and consumer multi-media game systems. Also, being upwardly software-compatible with the RC32300 family as well as bus- and upwardly software-compatible with the IDT RC4000 family, the RC4640 will serve in many of the same applications. And, the RC4640 supports applications that require integer digital signal processing (DSP) functions.
●The RC64475 and RC64575 processors offer a direct migration path for designs based on IDT’s RC4650 processors, through full pin and socket compatibility.
●The RC4640 brings 64-bit performance levels to lower cost systems. High performance is preserved by retaining large on-chip two-way set-associative caches, a streamlined high-speed pipeline, high bandwidth, 64-bit execution, and facilities such as early restart for data cache misses.
●These techniques allow the system designer over 3.2 GB/sec aggregate internal bandwidth, 500 MB/sec bus bandwidth, almost 352 Dhrys-tone MIPS, 89MFlops, and 133.5 M Mul-Add/sec. An array of tools facilitates rapid development of RC4640-based systems, allowing a wide variety of customers access to the processor’s high-performance capabilities while maintaining short time-to-market goals.
