The R2000 design came, in about 1987, from the Stanford MIPS project, which stood for Microprocessor without Interlocked Pipeline Stages.
Like the AMD 29000, the R2000 has no condition code register considering it a potential bottleneck. The program counter can be read like other registers.
The CPU includes an MMU that can also control a cache, and the CPU can operate as big-endian or little-endian. There is a FPU, the R2010.
Versions include the MIPS R3000 and MIPS R4000.
