Homework Answers
d. clock rate
Explanation: CPU clock speed measures how many clock cycles a CPU can perform per second. For example, a CPU with a clock rate of 1.8 GHz can perform 1,800,000,000 clock cycles per second.

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
1000000
Typically, processors’ performance is measured using a wide...

Which the following is the best performance measure of a program running on two different computers: computer clock rate of computer, program execution time, total number of clock cycles for the program running on the computer, total number of high-level instructions, or total number of low-level instructions? Explain why by pointing out the limits of each performance metrics. b. What is CPI and average CPI? What is the average CPI of a machine with two types of instructions: A: CPI...

(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....

You look at compilers as a way to improve performance. Your outdated compiler produces an instruction count of 2 times 10^9 instructions which execute in 1.3 sec. a) What is the average CPI of the program if the clock period is 0.5 ns? b) A new compiler generates only 1 times 10^9 instructions, with a CPI of 1.2. On the same processor (same clock), what speedup does the new compiler produce?

Computer system designers look for ways to improve system performance by advances in technology or change in design. Examples include the use of parallel processors, the use of a memory cache hierarchy, and speedup in memory access time and I/O transfer rate due to technology improvements. Explain with reasons, which internal and external memories, and input/output will be used in your design to further improve computer system performance. Also, justify how you can organise/connect them all to maintain the computer...

1. Cache memory (8pts) Consider adding cache to a processor-memory system design. The microprocessor without cache needs 12 clock cycles to read a 16-bit word from the memory. With cache, it takes only 4 clock cycles if the data happens to be in the cache and a total 20 clock cycles including the cache misses. a. What is the performance ratio of the cache system to the non-cache system given a hit rate of 80%? b. For what hit rate...

Suppose a computer M3 has an average CPI of 2.7 and a clock rate of 3.7 GHz. Please answer the following: (a) Calculate the runtime for a program P with 22,933 instructions, which uses an accelerating co-processor 45 percent of the time, and (b) determine how much faster (or slower) the accelerator needs to run for P to run 1.5 times as fast on M3 with the faster (resp. slower) accelerator.
