The Instruction Cycle and the Execution Cycle in RAM The steps in the basic cycle involved in processing a program statement in RAM are shown at left in the figure. This process is called the instruction cycle since it must be performed for every instruction to be executed. The amount of time required to complete the instruction cycle is referred to as the execution cycle, shown at right in the figure .
The Machine Cycle The instruction cycle and one or more execu-tion cycles create a machine cycle. Machine cycles are measured in micro-seconds. The faster your computer can process machine cycles, the faster it can process data.
