IDT79RC4640 Low-Cost Embedded 64-bit RISControllerw/ DSP Capability

PublishTime：2020-05-29

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 internet working 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 Dhrystone 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.
