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

Homework Answers

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.

In an unpipelined processor, instruction throughput is exactly one per cycle. A pipelined processor has amortized throughput of one instruction per cycle, but only if stalls can be avoided; in practice throughput is something less than 1 and depends on things like the quality of the compiler and memory access patterns. Given that pipelining actually decreases IPC, how can we justify the added complexity it forces on the design?
