Explain the characteristics of instruction and execution time.
Some of the characteristics of instruction time are as follows:
- The instruction time is also known as the I-time.
- It is the time taken by the Control Unit to get an instruction from memory and to load it to the register.
- The time also includes the taken by the CU for instruction decoding and to find out the location of the required data.
Some characteristics of execution time are:
- It is the time required by the control unit to move data from the memory to the registers in the ALU, the ALU is responsible for the execution of instructions on this data.
