What is a clock cycle and clock speed? [closed]

April 13, 2023 by Tarik

The speed of a computer processor, or CPU, is determined by the Clock Cycle, which is the amount of time between two pulses of an oscillator. Generally speaking, the higher number of pulses per second, the faster the computer processor will be able to process information. The clock speed is measured in Hz, typically either … Read more

How many CPU cycles are needed for each assembly instruction?

February 24, 2023 by Tarik

Modern CPUs are complex beasts, using pipelining, superscalar execution, and out-of-order execution among other techniques which make performance analysis difficult… but not impossible! While you can no longer simply add together the latencies of a stream of instructions to get the total runtime, you can still get a (often) highly accurate analysis of the behavior … Read more
