When a program is run on Computer X, 70% of the execution time is CPU time . A better Computer Y reduces the execution time by 25%. It is know that Computer Y has a clock rate of 2.4 GHz, and it takes Computer Y 20% more clock cycles to execute the program. In addition, Computer Y can only reduce CPU time. What is the clock rate in GHz of Computer X? The answer must have exactly one digit after the decimal point, even if it is zero, e.g. 2.0 or 0.9.

A program (or a program task) takes 150 million instructions to execute on a processor running at 2.7 GHz. Suppose that 50% of the instructions execute in 3 clock cycles, 30% execute in 4 clock cycles, and 20% execute in 5 clock cycles. What is the execution time for the program or task? Suppose the processor in the previous question part is redesigned so that all instructions that initially executed in 5 cycles and all instructions executed in 4 cycles...

(6 pts) A program P2 is executed on computer system B, which has a 2.8571429 GHz clock frequency. A programmer writes code to read processor performance monitoring registers after the program completes (Intel refers to the part of the CPU that can be used to collect run-time information as the Performance Monitoring Unit or PMU). The performance monitoring unit indicates that 23,118,471,971 user instructions were executed (just the instructions of P2 excluding OS and overhead instructions) in 53,866,039,692 clock cycles....

Figure 1: each block gives the number of different types of instructionsConsider a program with the execution flow shown in Figure 1. There are in total 3 types of instructions used in this program: Type 1 (in-processor calculation): execution rate as 1 per clock cycle; Type 2 (memory access): each instruction takes 2 clock cycles for execution; Type 3 (loop control): each instruction takes 2 clock cycles for jump into the loop block or 3 clock cycles for jump to the block after...

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...

Design and implement a C Language program that measures the
performance of given processors.
There are several metrics that measure the performance of a
processor. We will be using the following 3 measures:
1.CPI (clock cycles per instruction) = #clock cycles
/#instructions
2.CPU execution time = #instructions x CPI x clock cycle time
.
cylce time = 1/CPU clock rate in hertz units
3.MIPS (mega instructions per second)= #instrucrions/ CPU X
