What is a command cycle? What is a machine cycle? What is a clock cycle? What is the relationship between the three?

Instruction cycle: The time when a command is taken and executed.

Machine cycle: Also known as the CPU cycle, it takes a long time for the CPU to access the memory. Therefore, it is defined by the shortest time for reading a script from the memory.

Clock cycle: It is usually called a cycle pulse or a T cycle. The most basic unit for processing operations, that is, CPU clock speed.

 

Relationship between the three elementsThe command cycle is usually expressed by several machine cycles, and the machine cycle contains several clock cycles.

 

Example: The CPU cycle is also called the machine cycle, which is generally the shortest time from memory (.

A. Read a command B. Write an instruction

C. Read and Write a command D. Execute a command
