1.3 What is an R10000 Microprocessor?

Instruction Decode And Rename Unit

The instruction decode and rename unit has the following characteristics:

  • it processes 4 instructions in parallel
  • it replaces logical register numbers with physical register numbers (register renaming)
    • it maps integer registers into a 33-word-by-6-bit mapping table that has 4 write and 12 read ports
    • it maps floating-point registers into a 32-word-by-6-bit mapping table that has 4 write and 16 read ports
  • it has a 32-entry active list of all instructions within the pipeline.
