3. Given a program written in a HLL, consider two compilers: Compiler, results in a dynamic instruction count of 1109 instrs. and an execution time of 1.1 seconds. Compiler 8 results in a dynamic instruction count of 1.2109 instrs. and an execution time of 1.5 seconds. a) If the processor has TCLK=1ns, find the average CPI for each executable. Which compiler is better? b) If the two executables are run on two different processors and they have the same teXE, then find fB/fA( ratio of their fCLK)
