R3000

The MIPS 1 instruction set is small compared to those of the contemporary 80x86 and 680x0 architectures, encoding only more commonly used operations and supporting few addressing modes.

In addition to the CPU core, the R3000 microprocessor includes a Control Processor (CP), which contains a Translation Lookaside Buffer and a Memory Management Unit.

It was fabricated in a 1.2 μm complementary metal–oxide–semiconductor (CMOS) process[1] with two levels of aluminium interconnect.

When advances in technology rendered it obsolete for high-performance systems, it found continued use in lower-cost designs.

Companies such as LSI Logic and Integrated Device Technology developed derivatives of the R3000 specifically for embedded systems.
