A program has a total of 10 million instructions. The instructions are divided into 3

      classes . The CPI and the frequency of occurrence of each class is as given below

                              Class           CPI        Frequency

                                A                 1               50%

                                B                 3               30%

                                C                 5               20%

What should be the minimum clock frequency to execute the program in no more than 20 milliseconds?

A particular Instruction Set Architecture (ISA) has four classes of instruction: load/store, fixedpoint, floating-point, and branching. Load/store instructions all require 2 clock cycles to execute, fixed-point instructions all execute in one clock cycle, floating-point instructions all require 8 clock cycles to execute, and branch instructions take one clock cycle if the branch is successful and two clock cycles if the branch fails. A program is run on a processor with this ISA and measurements show that 20% of the instructions...

You have a task to improve performance of your processor on scientific applications where floating-point operations play a critical role. You know that when you are running your program on a processor in a base configuration, the fraction of floating-point instructions is 30% of the total instruction count. The CPI for floating-point instructions is 1.5, and CPI for all other instructions is 1.3. You decided to introduce new dual-op instructions (like multiply-add) and other performance improvements which will reduce the...

Please write a java program Instructions Your goal is to take N integer inputs from the user -- N's value will be given by the user as well. You can assume the user provides a valid value for N, i.e., >0. Store the input integers in an array of size N in the order they are provided. These tasks should be done in the main() method. Create a new method called checkArray() that will take the previously created array as...
