The throughput of a superscalar processor depends on the number of instructions it can issue per clock cycle. Early superscalar processors were able to issue two instructions per clock. Later processors could issue four instructions per clock. Although massive progress has been made in processor parameters such as clock speed or cache size, it is unlikely that we will see 64?way or 128?way superscalar processors. Why?
What will be an ideal response?
Throughout much of computing the law of diminishing returns applies. Superscalar processing relies on taking a
handful of instructions and executing them in parallel without changing the meaning (semantics) of the code. It
is often easy to find two instructions that can be executed in parallel without dependencies. It get progressively
more difficult as the number of contenders for parallel execution increases.
