Editor to share with you what is the relationship between machine cycle and clock cycle, I believe that most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article. Let's learn about it!

The relationship between machine cycle and clock cycle is that a machine cycle consists of several clock cycles. In a computer, the time required to complete a basic operation is called a machine cycle. The clock cycle, also known as the oscillation period, is the smallest unit of time in the time series.

Detailed introduction:

The machine cycle is also called the CPU cycle. In a computer, in order to facilitate management, the execution process of an instruction is often divided into several stages (such as fetch, decoding, execution, etc.), and each stage completes a basic operation. The time it takes to complete a basic operation is called the machine cycle. In general, a machine cycle consists of several clock cycles.

The clock cycle T, also known as the oscillation period, is generated by the monolithic on-chip oscillation circuit OSC, which is often defined as the reciprocal of the clock pulse frequency and is the smallest time unit in the time series. For example, if the clock frequency of a single-chip microcomputer is 1MHz, its clock cycle T should be 1 μ s. Because the clock pulse is the basic working pulse of the computer, it controls the working rhythm of the computer and unifies every step of the work of the computer to its pace. Obviously, for the same type of computer, the higher the clock frequency, the faster the computer will work. However, because different computer hardware circuits and devices are not exactly the same, the clock cycle frequency range they need is not necessarily the same.

The above is all the contents of the article "what is the relationship between machine cycle and clock cycle". Thank you for reading!
