NettetOn x86, instruction execution performance depends far, far more on context than it does on the actual instruction -- virtually all instructions can optionally be loads or stores, for example. And purely register-to-register instructions are going to depend in complex ways on the pipeline state on modern CPUs. Nettet19. jan. 2024 · When a device raises an interrupt at let’s say process i, the processor first completes the execution of instruction i. Then it loads the Program Counter (PC) with the address of the first instruction of the ISR. Before loading the Program Counter with the address, the address of the interrupted instruction is moved to a temporary location.
