Question

When the machine cycle performs the execute step, it is ________?

Answer 1

The execute step in a machine cycle carries out the operation specified by the instruction, with the execution path varying depending on the instruction and the machine's state.

Step-by-step explanation:

When the machine cycle performs the execute step, it is neither a process in which the system follows the same path for every cycle nor a process in which the system follows a different path for every cycle. Instead, during the execute step, the machine cycle carries out the operation commanded by the instruction. The path followed depends on the specific instruction being executed. For instance, some instructions may lead to arithmetic computations, others to data movement, and others may alter the flow of control in the program.

The machine cycle typically consists of several steps, like fetching the instruction, decoding it, executing it, and then storing the result. The execution path taken during the execute step can vary widely depending on the particular instruction and the current data and state of the machine.

Answer 2

It is in execute mode. There are four steps in the machine cycle: fetch, decode, execute and store. The steps performed by the computer processor for each machine language instruction received. This 4 process cycle includes reading and interpreting the machine language, executing the code and then storing that code.
