Problem 1 (10 points): MP3 Warmup
In order to allow for more interesting patterns in “Life” it is necessary to use a larger board.
Try writing the code for a subroutine that gets one character of user input that could be either ‘0’-
‘9’ or ‘A’ - ‘V’ and returns the binary value of 0-31 as needed.
Specifics
1. Open a terminal, and type 'ece190' (yes, you need to run the 'ece190' script).
2. Execute 'cd mp3`
3. Execute 'ls -l' and you will see ‘mp3.asm'. If you do not please contact your TA
immediately.
4. MAIN is complete and given, and calls PRINT_ROW 16 times (one call per row).
5. GET_INPUT needs to meet the following specification:
• Inputs: NONE
• Outputs: R0 - Numeric equivalent of number entered by user.
• Registers must be callee-saved.
• Note: No invalid inputs (i.e. ‘Z’) will be given to the program.
6. No test vector files or make commands have been provided.
