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.

Computer Science Using memory-mapped I/O and polling, write a function print_string that prints a string onthe display, without using any system call. The address of the string is passed in register $a0and the string must be null-terminated. Test this function by calling it from the main function.Make sure to activate the “Keyboard and Display MMIO Simulator”.
This is COmputer Architecture! this is about hamming code PLEASE WRITE THE CODE IN MIPS ASSEMBLY LANGUAGE! Assignment for Computer Architecture The assignment is to create a MIPS programs that the determines what the ECC code should be for a given number (an 8-bit byte). ECC Hamming codes are explained on pages 420-424 in your text. The codes you create are to work for 8-bit positive numbers as these are simpler to work with than larger numbers. The program is to request the user to enter a byte of data (a positive integer in the range of 0 to 255 in decimal) and then create the 12-bit Hamming code as described in your text (see above). The program is to then output this (with an appropriate label) in hex. Requirements: Make certain that you have lots of comments in your code as this is in MIPS. Also make the code neat: line up the instruction columns, the register columns, and the comment fields For this assignment, turn in your code, a screenshot showing a working for a test…
NAND2TETRIS HARDWARE SIMULATOR 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.). In other words, the HiLoMux can be used to select anibble from a byte please use the skeleton program below CHIP HiLoMux{ IN in[8], sel; OUT out[4]; PARTS: }
Using pep9 Write a machine language program to add the three numbers 2, –3, and 6 and output the sum on the Pep/9 output device. Store the 2, –3 and 6 in hexadecimal in appropriate memory locations. Do not use the subtract, negate, or invert instructions (only addition instructions). The solution should be submitted as a text file showing the program listing with associated memory addresses and comments in addition to a screenshot showing the completed execution in the Pep/9 simulator
3. Draw the memory map for 8 bytes starting at 0x2000_0030 as shown in the form given above.
Assume that A and B are arrays of 64-bit integers, and C and i are 64-bit integers. Assume that all data values and their addresses are kept in memory (at addresses 1000, 3000, 5000, and 7000 for A, B, C, and i, respectively) except when they are operated on. Assume that values in registers are lost between iterations of the loop.
Create a code (assembly language) that allows PIC18 microprocessor, which is connected to 7-segment display, to repeatedly count down from 100 to 00. The commands which are allowed are MOVLW, ADDLW, MOVWF, ADDWF, MOVFF, DECF, COMF, GOTO. No loops are allowed please. eg. of increment code: CLRF TRISCCOUNT EQU 0x25MOVLW 00HRND1MOVWF PORTCINCF PORTC, FMOVF PORTC, WDAWGOTO RND1
