Q1. A computer has a five-stage instruction pipeline of one cycle each. The five stages are: Instruction Fetch (IF), Instruction Decode (ID), Operand Fetch (OF), Instruction Execution (IE), and Operand Store (OS). Consider the following code sequence, which is to be run on this computer.: STORER16,#12LOADR16,M[8]SUBR7,R16,R4BNET1ADDR5,R1,R4SUBR15,R5,R4NOP;R1612;R16M[8];R7R5-R4;BranchtoT1ifR7notnegative;R5R4+R1;R15R5-R4;Donothing a. Draw a pipeline diagram to show what happens when the BNE instruction is true. b. Identify where the occurrence and the type of hazard is in the code. c. Compute the throughput and the speedup of the code
