- Using MIPS assembly language, write a MIPS programs that the determines what the ECC code should be for a 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. the following code is not working and has errors: # Prompt user for inputli $v0, 4 # system call for printing stringla $a0, prompt # prompt stringsyscall # Read input byteli $v0, 5 # system call for reading integersyscallmove $t0, $v0 # store the byte in register $t0 # Calculate ECC Hamming codesrl $t1, $t0, 4 # extract the first 4 bitsxor $t1, $t1, $t0 # calculate parityand $t1, $t1, 0b1011 # mask out irrelevant bitssll $t1, $t1, 8 # shift left by 8 bitssrl…arrow_forward4.

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…arrow_forward
