Dealing with branches in pipelining
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 …
Dealing with branches in pipelining
Did you know?
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.

WebRecall that there are three ways of dealing with a branch: (1) Assume the branch is not taken, and if the branch is taken, flush the instructions in the pipe after the branch, then insert the instruction pointed to by the BTA; (2) the converse of 1); and (3) use a delayed branch with a branch delay slot and re-ordering of code (assuming that ...
