Since there is a limit on the speed of hardware and the cost of faster circuits is quite high, we have to adopt the 2 nd option.

CHAPTER 2 Pipelining Pipelining: Basic and Intermediate Concepts

In computer engineering, instruction pipelining is a technique for implementing instruction-level parallelism within a single processor. Pipelining attempts to keep every part of the processor busy with some instruction by dividing incoming instructions into a series of sequential steps (the eponymous "pipeline") performed by different processor units with different parts of instructions processed in parallel. WebBranches make flow dynamic and determine which instruction is the supplier of data • Example: The instruction OR depends on DADDU or DSUBU? We must ensure that we …

WebSince 75% of branches are forward, this contributes ; cycles. Similarly, 15% of backward branches suffer a 2 cycle penalty, adding ; cycles. The total branch penalty is thus 0.35 + 0.75 + 0.075 = 1.175 cycles. Since branches make up 20% of all instructions, the penalty to the CPI is ; cycles. This makes the new CPI 1.235.
