The following byte sequence is the machine code of a program function compiled with the Y86- 64 instruction set. The memory address of the first byte is 0x300. Note that the byte sequence is written in hex-decimal form, i.e., each number/letter is one hex-decimal number representing 4 binary bits, and two numbers/letters represent one byte. 630030F3020000000000000030F11E000000000000007023030000000 00000601061316211761F0300000000000090- Please write out the assembly instructions (in Y86-64 instruction set) corresponding to the machine codes given by the above bytes sequence, and explain what this program function is computing.

This is a program that needs to be written in AssemblyGOAL: Write a PEP/8 machine language simulator 1. Use an array to represent the memory. 2. Use variables or arrays for the PEP8 registers. I recommendputting it all into a structure. I also recommend using an array of16 bit values for A, X, PC, SP so that you can use the r bit fromthe instructions to point directly to A or X. You do NOThave toinclude the Status bits. 3. Use unions of structures to break up the registers andinstructions into the correct bits (for example, use a structurethat can be unioned to break up the 8 bit specifier into thefollowing bit combos (4, 1, 3), (5, 3), (7, 1), (8). This willallow you to instantly extract the instruction, register andaddressing modes from each instruction. Also use a union to breakup the 16 bit operand into two 8 bit values. 4. Have the instructions be inputted either through the commandline or better yet, through a file, in the following format foreach instruction: a. 6 Hexadecimal…

Using this code, show a scenario if all three processes want to enter their critical sections.
MIPS Simulator QtSpim: You are to have a complete program in MIPS assembly language that behaves exactly as the included C program. This program contains four functions in addition to the main() one. Your solution must contain all five C routines as they have been coded in the example. Make sure to run the program in MIPS and show the same output on MIPS as well to make sure there are no errors. Below is the five C routines and attached is the image of what the output must print out on QtSpim. #include <stdio.h> int getMax(int arr[], int n){int mx = arr[0];for (int i = 1; i < n; i++)if (arr[i] > mx)mx = arr[i];return mx;}void countSort(int arr[], int n, int exp){int output[n];int i, count[10] = { 0 };for (i = 0; i < n; i++)count[(arr[i] / exp) % 10]++;for (i = 1; i < 10; i++)count[i] += count[i - 1];for (i = n - 1; i >= 0; i--) {output[count[(arr[i] / exp) % 10] - 1] = arr[i];count[(arr[i] / exp) % 10]--;}for (i = 0; i < n; i++)arr[i] = output[i];}void…
80x86 Intel Assembly language Write an 80x86 Intel assembly language program: Declare two integer arrays and initialize the first one with 7, 6, 5, 4 and 3. Initialize the second one with 3, 6, 9, 10, 15 Declare the third array of the same size but do not initialize. Your program must initialize ESI and EDI to have the addresses of the array1 and array2 respectively. Use EBX and place the address of the third array in that register. Use these registers to add the first element of the first array to the first element of the second array and place the result in the third array. Updated the values of these registers so all of them refer to the next location.
Q1- Write a program in assembly language for the 8085 microprocessor to send one byte of data located at the memory address (3000H) using SOD at a baud rate of 1200. Information: The 8085 processor operates at a frequency of 3.072 MHz. When sending the required byte, you must adhere to the following: The two high bits of the start bits must be sent, after that the data bits are sent, after that the low bit of the stop bit is sent. The following flowchart will help you. The solution must be integrated and include the calculation of the baud rate delay time Transmit Set up Character Bit Counter • Send Start Bit No Wait Bit Time Get Character in Accumulator Output Bit Using Do Wait Bit Time Rotate Next Bit in Do Decrement Bit Counter Is It Last Bit? Yes • Add Parity if Necessary Send Two Stop Bits Return (a)
Q2. Interface 4 digit displays (each digit is a 7-segment display) to the 80386DX microprocessor (32 bit data bus and 32 bit address bus) using 8255 PPI. The 8255 should function at I/O addresses that start at 200H. Then write a program to initialize the 8255 and multiplex the 4 digit display where the data, in 7-segment code, that is to be displayed is stored at memory location 2000H: 0100H.
