Question

Differentiate between instruction and arithmetic pipeline

Answer 1

Answer:

Instruction pipelining is the overlapping of instructions in the CPU datapath based primarily on the defined instruction cycle for the processor. Arithmetic pipelining is the overlapping of computation within the ALU (arithmetic logic unit) or FPU (floating-point unit).

Answer 2

Differences between instruction and arithmetic pipeline are:

Arithmetic pipeline:

• An arithmetic pipeline divides a problem into subproblems that may be solved separately in pipeline segments.
• Multiplication, floating-point operations, and several other calculations are performed with it.

Instruction:

• A stream of instructions can be executed by overlapping the fetch, decode, and execute phases of an instruction cycle.
• This strategy is used to increase the throughput of a computer system.
