Step 1 Programs are the set of lines of code that is used to provide instructions to the computer. The instructions are provided to perform certain tasks. The instructions are implemented by the programmer using the programming language according to the requirement. The instructions are given by the program accordingly. The program is used to solve everyday problems, it is used for problem-solving. It can be used to solve complex problems in seconds. Examples of binary code are 101 is the representation of 5 in digital, etc. arrow_forward Step 2 The importance of binary code are as follows: Images are most typically created in systems with the help of tiny colored squares known as pixels. Binary codes are used to represent images. In particular, understanding the binary digits of image pixels paves the way to image manipulation applications like trying to hide one image inside the other. For carrying out the instructions, computer programs employ a very specialized logic…

This is Computer Machine Architecture! this is Hamming code in MIPS assembly language 1. when I input a 154 (the example in the book). It should have given an output of 0x72A. the assignment: This assignment is to create a MIPS programs that the determines what the ECC code should given number (an 8-bit byte). 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. Make sure 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 like the format below

A barcode scanner for Universal Product Codes (UPCs) verifies the 12-digit code scanned by comparing the code's largest digit (called a check digit) to its own computation of the check digit from the first 11 digits as follows: 1. Calculate the sum of the digits in the odd-numbered positions (the first, third,..... eleventh digits) and multiply this sum by 3. 2. Calculate the sum of the digits in the even-numbered position (the second, fourth....tenth digits) and add this to the previous result. 3. If the last digit of the result from step 2 is 0, then 0 is the check digit. Otherwise, subtract the last digit from 10 to calculate the check digit. 4. If the check digit matches the final digit of the 12-digit UPC, the UPC is assumed correct By using C++ write a program that prompts the user to enter the 12 digits of a barcode separated by space. The program should store the digits in an integer array, calculate the check digit, and compare it to the final barcode digit. If the digits…

5- Create an algorithm in assembly that will compute the area of a triangle. Here is the state of the memory when starting the algorithm: Base is stored as an 8 bit unsigned integer in a memory location pointed to by the special register X. Height of the triangle is stored as an 8 bit integer in a memory location pointed to by the special register Y. Your computed area of the triangle should be stored in memory at a location pointed to by the special register Z. If multiple rows of memory are required, then Z indicates the starting address. Requirements Clearly list the assembly commands required for this algorithm. How many rows of program memory are required for this algorithm? How many clock cycles (according to the AVR ISA) are required for this algorithm? What addressing mode is used for each assembly instruction?
