Problem 3. (25 pts.) Compilers can have a profound impact on the performance of an application. Assume that for a program, compiler A results in a dynamic instruction count of 1 billion instructions and has an execution time of 1.1 seconds, while compiler B results in a dynamic instruction count of 1.2 billion instructions and an execution time of 1.5 seconds. A) Find the average CPI for each program given that the processor has a clock cycle time of 1...

We find a way of improving the floating point instruction performance of a machine and make it run 15 times faster. In a given program, how many of the instructions must be floating point to achieve an overall improvement of 4? We have another way of achieving the required speedup of 4 in our computer. Instead of improving the floating point instruction performance, we improve the clock rate. We would like to obtain that magical speedup of 4 for our...

I need help with the following Computer Architecture question: Consider two different implementations, M1 and M2, of the same instruction set. There are three classes of instructions (A, B, and C) in the instruction set. M1 has a clock rate of 90 MHz and M2 has a clock rate of 80 MHz. The average number of cycles for each instruction class and their frequencies (for a typical program) are as follows: Instruction Class Machine M1 – Cycles/Instruction Class Machine M2...
