) A program is run on a 2.1 GHz processor. The program?s code consists of 10,000instructions, with the following instruction mix and clock cycle count:Instruction Type Instruction Count(# of such instructions)Clock Cycle Count(# of clock cycles / instr.)Integer arithmetic 5000 1Data transfer 3000 2Floating point 1500 2Control transfer 500 2Determine this program?s (i) effective CPI and (ii) the percentage of time doing FP ops.(b) A new computer with enhanced architecture run 16 times faster than the originalmachine, but it is usable only 1/8 of the time. What is the speedup?(c) A program takes 15 seconds to execute on a single 1.8GHz processor. 30% of theprogram is sequential. Assuming zero latency and perfect parallelism in the remainingcode, how long should the code take on a 20 core processor machine?(d) A computer uses instruction pipelining with P=4 stages named FD, DO, EX, WO.Each stage takes T seconds to perform its task. Suppose you have N=9 instructions inyour program which has a branch from instruction 4 to 8. Draw a figure to show whathappens over time as each instruction is processed. Indicate the branch penalty.Question 2. Consider the following code sequence:i: R7 R12+R5i+1: R8 R7-R12i+2: R5 R8+R7(a) List the RAW dependencies, if any:(b) List the WAR dependencies, if any; rewrite code showing how to avoid them:(c) List the WAW dependencies, if any; rewrite code showing how to avoid them
