MIPS R2000

Realizes: Early SGI and DECstation workstations

Introduced in 1985 with a five-stage RISC pipeline, the MIPS R2000 leaned on single-cycle integer basics, a concise load/store ISA, and predictable control flow to keep each stage decoding, executing, and retiring in lockstep, which made it attractive to early SGI and DEC workstation vendors.

Examples

SGI Indigo workstation

The SGI Indigo workstation used the R2000 (and R3000) to deliver graphics and engineering performance in the early 1990s, showcasing its pipeline-driven throughput.
