Instruction cycle control

[bob]

You grab the next instruction from memory right away. The program counter holds that address you need. Control signals fire off to load it quick. I see how the bus moves data without delay. Timing circuits keep every pulse aligned here. You decode the bits once it arrives inside. Opcodes get broken apart by the decoder unit. I notice operands get sorted during this step. Branches might alter the flow based on flags. Control logic decides if more fetches follow next.
Perhaps memory reads take extra cycles you watch. The sequencer herds those micro steps along. You execute the operation after decoding finishes. Arithmetic units crunch numbers under tight control. I recall memory writes happen when needed too. Signals route data to the right spots fast. Or interrupts pause the whole cycle you know. Handling them requires saving states carefully first. Control units manage these switches without missing beats. You resume from where things left off later.
Hardwired paths speed up common instructions you use. Microcode allows changes for rare cases instead. I think flexibility comes at a small cost though. Clock edges trigger each phase in order. You adjust based on instruction length sometimes. Partial overlaps help pipelines run smoother now. But hazards force stalls in the stream ahead. Control resolves dependencies before they pile up. Perhaps register files update only at safe times. Then results feed back into later cycles.
