1.7 (16 pts) [15] Compilers impact application performance, sometimes dramatically. Assume that for a program, compiler A results in a dynamic instruction count of 1.0E9 and has an execution time of 1.1 s, while compiler B results in a dynamic instruction count of 1.2E9 and an execution time of 1.5 s. nEy means nx10. Call the computer running Compiler A's code P1 and B's code P2. (3 pt) What type of instructions are referred to by the phrase "dynamic instruction count"? a. b. (2 pts) Example 1.6.4 in the zyBook teaches us that CPI- CPU Clock Cycles/ Instruction Count. We also know CPU Clock Cycles CPU Time x CPU Rate. We can combine the two to get CPI = CPU Time x CPU Rate / IC. CPU Rate is usually shown as f. Find the CPI for each program given that the processor has a clock cycle s. Clock cycle time (sec/cycle) is the inverse of CPU Rate (cycle/sec) On page 29 of NIST's 2006 publication "The International System of Units" (see the Articles folder in our Google Drive), the following table appears: Table 5.
