RM7000AMicroprocessor with On-Chip Secondary Cache Data Sheet
Released
3 Description
PMC-Sierras RM7000A 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 RM7000A 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. An optional external tertiary cache provides high-performance
capability even in applications with very large data sets.
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 RM7000A ideally suits high-end embedded control applications such as internetworking,
high-performance image manipulation, high-speed printing, and 3-D visualization. The RM7000A
is also applicable to the low end workstation market where its balanced integer and floating-point
performance and direct support for a large tertiary cache (up to 8 MB) provide outstanding price/
performance.
