RM7065A™ Microprocessor with On-Chip Secondary Cache Data Sheet

Preliminary

3 Description

PMC-Sierra’s RM7065A is a highly integrated symmetric superscalar microprocessor capable of

issuing two instructions each processor cycle. It has two high-performance 64-bit integer units as

well as a high-throughput, fully pipelined 64-bit floating point unit.

The RM7065A integrates 16 KB 4-way set associative instruction and data caches along with an

integrated 256 KB 4-way set associative secondary. The primary data and secondary caches are

write-back and non-blocking.

The memory management unit contains a 64/48-entry fully associative TLB and a 64-bit system

interface supporting multiple outstanding reads with out-of-order return and hardware prioritized

and vectored interrupts.

The RM7065A ideally suits high-end embedded control applications such as internetworking,

high-performance image manipulation, high-speed printing, and 3-D visualization. The RM7065A

is also applicable to the low end workstation market where its balanced integer and floating-point

performance provide outstanding price/performance.
