Show the steps of the CPU fetch-execute cycle for the divide instruction

Answer #1

CPU fetch-execute cycle for the divide instruction:

The CPU stans for Cental processing Unit fetch the instructios from the main memory to the registers. The registers are known as immediate access store. The program counter holds one register.

The "program counter" contains the "memory address" of the upcoming instruction which is fetched from "main memory".

When it need to perform the arithmetic instructions like addition, multiplication, subtraction, and divide instructions, it orders the ALU to perform the instructions, which performs all "arithmetic and logical operations".

After that CPU decodes the instructions and execute the instructions.

The cycle repeated until there is no more instructions to perform.

A microprocessor has an increment memory direct instruction, which adds 1 to the value in memory location. The instruction has five stages: fetch opcode (four bus clock cycles); fetch operand address (four bus clock cycles); fetch operand (five bus clock cycles); add 1 to operand (three bus clock cycles) and, store operand (two bus clock cycles). How many bus clock cycles are required to execute the instruction
