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.

Write a counting program in MIPS assembly. The program should print the first sixteen powers of 2 beginning with 2^0 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).

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 Verilog code with testbench for 16-bit up/down counter with synchronous reset and synchronous up/down.If up/down is set the counter is up counter and if it is not set, the counter is a down counter.Execute the module code, testbench code, and the simulation results.
