WebJul 15, 2024 · Reciprocal throughput: The average number of core clock cycles per instruction for a series of independent instructions of the same kind in the same thread. For add this is listed as 0.25 meaning that up to 4 add instructions can execute every cycle (giving a reciprocal throughput of 1 / 4 = 0.25 ). WebThe instruction fetch unit also provides buffering, essentially acting as an on-demand unit to provide instructions to the issue stage as needed and in the quantity needed. Thus, as designers try to increase the number of instructions executed per clock, instruction fetch will become an ever more significant bottleneck, and clever new ideas ...
