Consider the following x86 machine instruction sequence:ADD EAX, EBXSUB ECX, EAXADD EBX, ECXThe first instruction adds the contents of the 32-bit registers EAX and EBX and stores the result in EAX. The second instruction subtracts the contents of EAX from ECX and stores the result in ECX. These instructions are to be executed in a pipelined instruction processor with the following 4 stages: fetch instruction (FI), decode instruction and calculate addresses (D

View answer

The instruction pipeline of a RISC processor has the following stages: Instruction Fetch (IF), Instruction Decode (ID), Operand Fetch (OF), Perform Operation (PO) and Writeback (WB). The IF, ID, OF and WB stages take 1 clock cycle each for every instruction. Consider a sequence of 100 instructions. In the PO stage, 40 instructions take 3 clock cycles each, 35 instructions take 2 clock cycles each, and the remaining 25 instructions take 1 clock cycle each. Assume that there are no data hazards and no control hazards.The number of clock cycles required for completion of execution of the sequence of instructions is ______.
