Consider the following statements: 1. A computer will have a multiply instruction 2. Multiply instruction will be implemented by a special multiply unit. Which of the following is correct? Correct Answer 1 is an architectural design issue while 2 is an organizational issue.

  • Computer architecture refers to those attributes of a system visible to a programmer, or those attributes that have a direct impact on the logical execution of a program.
  • As an example, it is an architectural design issue whether a computer will have a multiply instruction.
  • Computer organization refers to the operational units and their interconnections that realize the architecture specification.
  • An example, it is an organization issue whether the instruction (multiply instruction) will be implanted by a special multiply unit, or by a mechanism that makes repeated use of the add unit of the system

A 5-stage pipelined processor has Instruction Fetch (IF), Instruction Decode (ID), Operand Fetch (OF), Perform Operation (PO) and Write Operand (WO) stages. The IF, ID, OF and WO stages take 1 clock cycle each for any instruction. The PO stage takes 1 clock cycle for ADD and SUB instructions, 3 clock cycles for MUL instruction, and 6 clock cycles for DIV instruction respectively. Operand forwarding is used in the pipeline. What is the number of clock cycles needed to execute the following sequence of instructions? Instruction Meaning of instruction I0 : MUL R2, R0, R1 R2← R0 * R1 I1 : DIV R5, R3, R4 R5 ← R3 / R4 I2 : ADD R2, R5, R2 R2 ← R5 + R2 I3 : SUB R5, R2, R6 R5 ← R2 – R6
