The R5900 core was developed by Toshiba, exclusively for use in the Playstation 2 Emotion Engine (EE). It is similar to the R5000, but adds several SIMD (multimedia) instructions.

  • It implements almost all MIPS3 instructions, though it supports MIPS4's movn/movz.
  • It has a lot of SIMD instructions which allow you to do 128 bits register manipulations (vector rotations, etc)
  • It doesn't support load linked and store conditional instruction (ll/lld/sc/scd, MIPS2).

Toshiba tried to sell a derived core, the "ArTile TMPR7901B" (also known as TX79).
