MIPS Architecture - MIPS IV

MIPS IV

MIPS IV is the fourth version of the architecture. It is a superset of MIPS III and is compatible with all existing versions of MIPS. The first implementation of MIPS IV was the R8000, which was introduced in 1994. MIPS IV added:

• Register + register addressing for floating point loads and stores
• Single- and double-precision floating point fused-multiply adds and subtracts
• Conditional move instructions for both integer and floating-point
• Extra condition bits in the floating point control and status register, bringing the total to eight
