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 input li $v0, 4 # system call for printing string la $a0, prompt # prompt string syscall # Read input byte li $v0, 5 # system call for reading integer syscall move $t0, $v0 # store the byte in register $t0 # Calculate ECC Hamming code srl $t1, $t0, 4 # extract the first 4 bits xor $t1, $t1, $t0 # calculate parity and $t1, $t1, 0b1011 # mask out irrelevant bits sll $t1, $t1, 8 # shift left by 8 bits srl $t2, $t0, 4 # extract the first 4 bits again and $t2, $t2, 0b0111 # mask out irrelevant bits or $t1, $t1, $t2 # combine with the second 4 bits sll $t1, $t1, 4 # shift left by 4 bits srl $t2, $t0, 4 # extract the first 4 bits yet again and $t2, $t2, 0b0001 # mask out irrelevant bits sll $t2, $t2, 11 # shift left by 11 bits or $t1, $t1, $t2 # combine with the first two bytes ori $t1, $t1, 0x8000 # set the leftmost bit to 1 for error detection # Print ECC Hamming code in hex li $v0, 34 # system call for printing integer in hex move $a0, $t1 syscall # Exit program li $v0, 10 # system call for exit syscall .data prompt: .asciiz "Enter a byte of data (0-255): " THE PROGRAM ERRORS WHEN TRIED RUNNING: $t1, $t1, 0b1011 # mask out irrelevant bits Invalid language element: 0b1011 and $t2, $t2, 0b0111 # mask out irrelevant bits Invalid language element: 0b0111 and $t2, $t2, 0b0001 # mask out irrelevant bits Invalid language element: 0b0001 and $t1, $t1, 0b1011 # mask out irrelevant bits Invalid language element: 0b1011 and $t2, $t2, 0b0111 # mask out irrelevant bits Invalid language element: 0b0111 : and $t2, $t2, 0b0001 # mask out irrelevant bits Invalid language element: 0b0001 PLEASE FIX AND GIVE CORRECT CODE
