1. Introduction to the R10000 Processor
1.4 Instruction Queues
The processor keeps decoded instructions in three instruction queues, which dynamically issue instructions to the execution units. The queues allow the processor to fetch instructions at its maximum rate, without stalling because of instruction conflicts or dependencies.
Each queue uses instruction tags to keep track of the instruction in each execution pipeline stage. These tags set a Done bit in the active list as each instruction is completed.
