Textbook Question
Chapter 5, Problem 5.14HW
Write a version of the inner product procedure described in Problem 5.13 that uses 6 × 1 loop unrolling. For x86-64, our measurements of the unrolled version give a CPE of 1.07 for integer data but still 3.01 for both floating-point data.
- A. Explain why any (scalar) version of an inner product procedure running on an Intel Core i7 Haswell processor cannot achieve a CPE less than 1.00.
- B. Explain why the performance for floating-point data did not improve with loop unrolling.

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.

CHIP HiLoMux
{
IN in[8], sel;
OUT out[4];
PARTS:
}
Implement HiLoMux - This has one 8-bit input bus, in, and one 4-bit output bus, out. Alsopresent is a sel input, which is used to select what appears on out. Ifsel is false, then out should contain the lower 4-bits of in (i.e. in[0],in[1], in[2], in[3]). If sel is true, then out should contain theupper 4-bits of in (i.e. in[4] mapped to out[0], in[5], mapped toout[1], etc.).
Write a program in PLP assembly that repeatedly reads the value of the switches (address: 0xf0100000) and
displays a pattern on the LED array based on what switches. Each time the switch value is read, the pattern
should be displayed (regardless of whether the switch value has changed or not since the last time it was read).
The table below indicates the pattern that should be displayed for each possible switch setting.
- please use"sw" "li", labels, loops, "beq" and "lw" to create the code. The code is for assambly language and it will be compiled and run on PLPTool version 5.2.
