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.
