- Write assembly language programs to multiply and divide one 32-bit and one 16-bit number on the 8051 microcontroller. Write two different programs to multiply and divide one 32-bit and one 16-bit number. Your programs for multiplying and dividing should be named as ”multiply” and ”divide” respectively. Your main function name or label must be main. Your assembly source file is expected to work with EdSim51 8051 microcontroller simulator.Please,write a code for assembly language(8051 assembly language) DS1620 is a programmable temperature sensor. In this problem, this sensor to the MCU We will write a program to link. Explanation-Find the correct connection pins for DS1620 and connect to 8051.-We have a fan connected to P1.0 and a heater connected to P1.1.-Set the high temperature register to 90 and the low temperature register to 80.- If the temperature rises to 80, turn on the heater, if it rises to 90, turn on the fan. (this task so important,please do it)Programming Project: For Loops Write an Assembly Language Program that produces the Times Table for a specific integer value between 1 to 12. NOTE: You choose and hard code only one value (i.e. 7) and produce the times table for that value. Also note that since you are using registers and memory locations make sure that at each step you screen shot each result for each part of the Times Table. For example 7 x 12 = 84 but in Hexadecimal the value is 54. Sample code in C #include void main() ( int i, j; printf("Enter an integer: "); scanf("%d", &i); printf("Times %d Table\n", i). for(j = 0; j<= 12; j =j+1) { printf("%d x %d = %d\n", j, 1. j'i); } printf("\n");

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.
