Textbook Question
Chapter 5, Problem 5.15HW
Write a version of the inner product procedure described in Problem 5.13 that uses 6 × 6 loop unrolling. Our measurements for this function with x86-64 give a CPE of 1.06 for integer data and 1.01 for floating-point data.
What factor limits the performance to a CPE of 1.00?

Write a counting program in MIPS assembly. The program should print the first sixteen powers of 2 beginning with 20 with a space between each value. The output of the program should be exactly as follows:
1 2 4 8 16 32 64 128 256 512 1024 2048 4096 8192 16384 32768
Additional requirements for this problem: You must use a logical shift operation in your implementation. You must use a loop (i.e., a conditional branch that causes program instructions to repeat).
Description:
Implement a transistor-level schematic of a computational unit/ALU that can perform the
following operations.
XOR
● XNOR
Multiplication
Addition
Subtraction
● Rotate Shift Right
Magnitude Comparator
● Equality Comparator
The computational unit/ALU has a decoder to decode an instruction and a
multiplexer to select outputs of different operations.
Data inputs are 4-bit wide.
Make sure you test your design for all the operations listed above.

- Write a MIPS procedure that takes as its three parameters the starting address of an integer array, and two positive integers low and high, and returns the sum of the low’th through the high’th array elements. For example, for the array 3, 8, -1, 5, 4, 3, 9 and low and high values of 2 and 4, the return value should be 12 (since the sum of the 2nd through the 4th array elements is 8 + -1 + 5 = 12). Also, write a main program to test your procedure. Your main program should input the number of integers n in the array from the user (you may assume that n is at most 25), input the n integers, and then input the integers low and high. Your main program should then invoke your procedure, output the return value, and terminate. Your code must use the “standard” conventions for passing parameters and returning results.arrow_forwardHow can you teach an old dog new tricks? How can a bird in the hand be worth two in the bush?
