how does clock control various events(operations) from being occurred in desired sequence?what is the significance of a clock cycle time(i’ve heard that many operations can be issued in a single clock cycle)?
or simply,how does CPU controls operation ordering?
CPUs have various processing units (float, vector, integer), and pipelines of different lengths for each unit.
The clock determines at which speed it will go through all operations in a pipeline, each operation being a tick. Once it gets to the end, the result is sent back to cache/memory.
Multiple pipelines can be active at the same time.
That’s all I can tell you..
