The stage in which the CPU fetches the instructions from the instruction cache in superscalar organisation is
A. prefetch stage
B. D1 (first decode) stage
C. D2 (second decode) stage
D. final stage
Answer:A
The stage in which the CPU fetches the instructions from the instruction cache in superscalar organisation is
A. prefetch stage B. D1 (first decode) stage C. D2 (second decode) stage D. final stage
Explanation: In the prefetch stage of pipeline, the CPU fetches the instructions from the instruction cache, which stores the instructions to be executed. In this stage, CPU also aligns the codes appropriately.
