A call through a function pointer doesn't necessarily cause a pipeline clear, but it may, depending on the scenario. The key is whether the CPU can effectively predict the destination of the branch ahead of time. The way that modern "big" out-of-order cores handle indirect calls1 is roughly as follows:

WebAug 9, 2024 · The classic RISC design includes an instruction pipeline. Instead of running any of the five instruction stages in any given cycle, the pipeline allows all five stages to be performed. Of course, you can’t run all five stages of one instruction in a cycle. But you can queue up five consecutive instructions with an offset of one stage each.

WebFor example, MIPS uses the instruction RFE. If the pipeline can be stopped so that the instructions just before the faulting instruction are completed and those after it can be restarted from scratch, the pipeline is said to have precise exceptions. Generally, the instruction causing a problem is prevented from changing the state. WebA four-segment instruction pipeline combines two or more different segments and makes it as a single one. For instance, the decoding of the instruction can be combined with the calculation of the effective …

WebGiven an application where 20% of the instructions executed are conditional branches and 59% of those are taken.
