\nHi Amell,<\/p>\n

I just watched the entire series of MIPS tutorial that you have uploaded on your YT channel. First of all, thanks for that! It was awesome \ud83d\ude42<\/p>\n

Secondly, I have a few questions. As I am completely new to MIPS, I have received some tasks to do (from school) and do not know how they should be configured. Do you mind looking over them and give me some hints?<\/p>\n

For analyze.asm:
\nChange the program so that only every third character is printed. The program must still stop after “Z”.<\/p>\n

For hexmain.asm:
\nYou will now write a small subroutine, that converts numbers in the range 0 through 15 into a printable ASCII-coded character: ‘0’ through ‘9’, or ‘A’ through ‘F’, depending on the number. For numbers not in the range 0 through 15, some bits will be ignored. In file hexmain.asm, add an assembly-language subroutine with the following specification. Name: The subroutine must be called hexasc. Parameter: One, in register $a0. The 4 least significant bits specify a number, from 0 through 15. All other bits in register $a0 can have any value and must be ignored. Return value: The 7 least significant bits in register $v0 must be an ASCII code as described below. All other bits must be zero when your function returns. Required action: The function must convert input values 0 through 9 into the ASCII codes for digits ‘0’ through ‘9’, respectively. Input values 10 through 15 must be converted to the ASCII codes for letters ‘A’ through ‘F’, respectively. <\/p>\n

Thanks in advance!<\/p>\n

Best regards,
\nA.
