Answer:
ID - Instruction Decode
Explanation:
ID - Instruction Decode is one of the five stages (the second stage) in the Reduced Instruction Set Computer Pipeline. It follows the Instruction Fetch stage. It deals with register renaming and injects the decoded instruction into the active list. At this stage, the main data structures utilized are the following:
1. The register map table
2. The free list
3. The active list
4. The shadow mappers
Hence, In the class pipelined microarchitecture, control signals are decoded in the INSTRUCTION DECODE stage and pipelined along with the instruction for the subsequent stages
