PROBLEM-2: Consider the following code fragment to be executed in an 8-stage pipeline machine with Branch is resolved at the end of the 6th stage. Assume byte addressable memory PC address in hexadecimal 008 00A 100 102 120 122 Instruction PROC XOR How many cycles could be the branch penalty? Answer the following questions. Show your work for each question: L What is the number of pipeline fill cycles? iv. Calculate the Branch target address, in decimal? . BNE R1, R2, +8 INT 21 ENDP AQU X, Y Explain using RTL notation what happens during the Fetch, Decode, and Execute stages of the BNE instruction? w Calculate the CPI when executing the above code, for the following two cases: a. If Branch is never taken b. If Branch is taken.
