WebJust glancing at the clang output, it looks like it has one more taken branch and would thus take 24 instruction cycles. Still, Andy has the right answer. It depends, and without an instruction that has an effect (like changing a pin output) the optimizer will erase the loop. Webof a processor by issuing multiple instructions per clock cycle and by more deeply pipelining the execution units to allow greater exploitation of instruction-level parallelism. (This appendix assumes that you have read Chapters 3 and 4 completely; in addition, the discussion on vector memory systems assumes that you have read Chapter 5.)

WebIf you want your loop to execute once per clock cycle you have to add specific clock triggers so that the logic you have with in the loop is executed every clock cycle and the loop counter is incremented in the same clock cycle. This requires some form of state machine which in essence replaces the processor one has in a software system. Web3.1 The baseline performance (in cycles, per loop iteration) of the code sequence in Figure 3.48, if no new instruction’s execution could be initiated until the previ-ous instruction’s execution had completed, is 40. See Figure S.2. Each instruc-tion requires one clock cycle of execution (a clock cycle in which that
