DESCRIPTION
The IDT79R4640 is a low-cost member of the Integrated Device Technology, Inc. ORION family, targeted to a variety of performance-hungry embedded applications. The R4640 continues the ORION tradition of high-performance through high-speed pipelines, high-bandwidth 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.
