Description

The IDT79RV4650-200DP is a low-cost member of the IDT Microprocessor family, targeted to a variety of performance-hungry embedded applications. It continues the IDT tradition of high-performance through high-speed pipelines, high-bandwidth caches and bus interface, 64-bit architecture, and efficient control. The IDT79RV4650-200DP reduces the cost of this performance relative to other models by removing functional units that are frequently unneeded for many embedded applications, such as double-precision floating-point arithmetic and a TLB.
