Compute the CPI for a computer that runs its workload composed of two programs. Program 1 runs 1865751 instructions using 12451317 clock cycles, while program 2 runs 10114053 instructions using 13432898 clock cycles. The first program runs 2 times for each time program 2 runs.
A computer system contains a big endian byte addressable memory system with 8 separate memory modules. Each memory module is 32 bits wide and contains 134217728 cells. Cells within each memory module are numbered 0 through 134217727. a) If the memory employs high order interleaving, what is the 32-bit memory address of cell 1048578 within module 3? b) If the high order interleaved memory uses little-endian instead of big-endian storage order, what is the 32-bit memory address of cell 511 within module 1? c) If the memory employs low order interleaving, what is the 32-bit memory address of byte 1048575 within module 2? Bytes are numbered starting from 0. Express the address in hex. d) What is the main advantage of using low-order interleaved memory compared to using high-order interleaved memory?

Compare compilers A and B for a program, where compiler A results in a dynamic instruction count of 6.9x10^9 and an execution time of 5 seconds, and compiler B results in a dynamic instruction count of 5.1x10^9 and an execution time of 4 seconds. a. Find the average CPI for each program, given a processor clock cycle time of 2 ns. b. If the compiled programs run on two different processors with the same execution times, what is the relative speed of the processor clocks?
Suppose two CPU A and B have exactly the same circuits, but different clock frequencies. Answer the following questions: a) If the clock frequency of CPU A is 8MHz, how long is one clock cycle of CPU A? b) If the CPU A can execute 0.4 million instructions per second on average, how long is the average time to execute one instruction? c) What is the average number of clock cycle to execute one instruction for CPU A? d) The frequency of CPU B is 12MHz. What is the average number of instructions that can be executed per second?
Your favorite computer program (after being converted to MIPS assembly code, then to machine code) results in 2.5e8 instructions. Consider the three different CPUs and their clock rates and CPIs and determine how much time it would take each of them to execute this program. Lawrence’s computer with a clock rate of 3.32 Ghz and a CPI of 1.2.

O 3 CPI O 2 CPI O 5 CPI O None of them O 4 CPI Instruction Count 45.000 32,000 15,000 8,000 Cycles per Instruction 3 4 8 3
Assuming the same instruction mix listed in Problem 7, what is the average execution time across all instructions?
Question 20 Consider two different machines with two different instruction sets, both of which have a clock rate of 800 MHz. The following measurements are recorded on the two machines running a given set of benchmark programs. Instruction Type Machine A Arithmetic and logic Load and store Branch Others Machine B Arithmetic and logic Load and store Branch Others O 50 ms O 70 ms O 55.2 ms O 60 ms Instruction Count (millions) O None of them 8 4 2 4 10 8 2 4 Cycles per Instruction 1 3 4 With machine A, how long would it take to execute the program? 3 1 2 4 3
Calculate the CPU execution time (expressed in milliseconds) of a program with 10 million instructions on a 2.5 GHz CPU with the following basic instruction-type breakdowns and CPIs: Arithmetic: 60%, CPI = 2 Load & Store (assuming perfect caches): 25%, CPI = 5 Branching: 15%, CPI = 3 In addition, you are told that the overall cache miss rate for instructions is 1%, the overall cache miss rate for data is 3%, and the cache miss penalty is 100 cycles. You can ignore the hit time (consider it zero).
A certain microprocessor requires either 2, 4, 8, 12, or 16 machine cycles to perform various operations. A total of 17.5% of its instructions require 2 machine cycles, 12.5% require 4 machine cycles, 35% require 8 machine cycles, 20% require 12 machine cycles, and 15% require 16 machine cycles.Q) What is the clock rate (machine cycles per second) required for this microprocessor to be a “1 MIPS” processor?
Consider the execution of a program that results in the execution of 8 million instructions on a 400-MHz processor. The program consists of four major types of instructions. The instruction mix and the CPI for each instruction type are given below. What is the program execution time in the second? Instruction Type Arithmetic and logic Load/store with cache hit Branch Floating-point arithmetic operation Execution Time: sec CPI 3 4 3 9 Instruction Mix (%) 60 20 12 8
