I need help with this MIPS problem. I'm using MARS simulator to create a program that read 2 8 bit 2sc program arguments. Store them then convert and add together. Print the sum as a signed base 4 number to the console. The detailed information is listed below. Also I have no idea on the extra credit part. Please help. Thanks.

Lab Objective In this lab, you will develop a more detailed understanding of how data is represented, stored, and manipulated at the processor level. In addition to strengthening your understanding of MIPS coding, you will read a string input and learn how to convert ASCII characters into a base 4 number and print it to the console Lab Preparation Read chapters 1 and 9 from Introduction To MIPS Assembly Language Programming. Specification Functionality The functionality of your program will be as follows: 1. Read two 8-bit 2SC program arguments. These numbers may be entered as hex (using the "0x" prefix) or binary (using the "ob" prefix). The range of these inputs are: [0x80, 0x7F] in hex or [0b10000000, 0be1111111] in binary. Note that this range is [-128, 127] in decimal a. Hex inputs will be exactly 2 digits. b. Binary inputs will be exactly 8 bits. 2. Print the user inputs 3. Identify each number as hex or binary by looking at "ox" prefix for hex and "ob" prefix for 2SC binary. 4. Convert the ASCII strings into two sign-extended integer values. a. Convert the first program argument to a 32-bit two's complement number, stored in register $s1. b. Convert the second program argument to a 32-bit two' s complement number, stored in register $s2. 5. Add the two integer values, store the sum in $s0 6. Print the sum as a signed base 4 number to the console. Do not print any leading 0s. a. If the number is negative, print a negative sign and the magnitude b. If the number is positive, just print the magnitude 7. (Extra credit) Read in the program arguments as signed decimal numbers and print the sum as a base 4 value a. The program arguments can be any decimal number between -128 and 127. These arguments do not need a prefix, and will not have any leading zeros (e.g. the number 9 will entered as "9" not "e9") b. Note that the ASCII code for a negative sign ("-") is ex20. Two Parts Part A: Block Diagram & Pseudocode Before coding, you will first create a top level block diagram or flowchart to show how the different portions of your program will work together. Use https:L/www.draw.io or a similar drafting program to create this document. This diagram will be contained in the file Diagram.pdf. This diagram must be computer generated to receive full credit. Next, you will create pseudocode that outlines your program. Your pseudocode will appear underneath your header comment in Lab4.asm. You may modify your pseudocode as you develop your program. Your pseudocode must be present in your final submission Guidelines on developing pseudocode can be found here: Wr Part B: Assembly Code Write a program in MIPS to implement the functionality. Output An example of the expected output is given below. Your code's output format should match this output format exactly. New line characters are printed after each number representation. Here are several example program outputs: You entered the numbers: 0x35 0xF4 The sum in base 4 is: 221 program is finished running You entered the numbers: 0xCE Ob11110100 The sum in base 4 is -332 program is finished running You entered the numbers: 53 -12 The sum in base 4 is 221 program is finished running -- You entered the numbers: OxCE -12 The sum in base 4 is: -332 - program is finished running Syscalls When printing the integer values, you may use syscall system services 4 (print string) and 11 (print character). You may not use the following syscalls: 1 (print integer) 5 (read integer) 12 (read character) 34 (print integer as hexadecimal) 35 (print integer as binary) 36 (print integer as unsigned) You will lose a significant number of points if you use any of these syscalls. See the rubric for more details Input In this lab you will obtain two user inputs, not using a syscall, but by using program arguments. The user will enter two values separated by one space as indicated above. These numbers will be sign-extended to 32 bits and stored in $s1 and $s2.

Text Segment Program Arguments Bkpt AddressCode Basic Source When program arguments are entered and the code is run, $a0 initially contains the number of program arguments entered (program arguments are separated by spaces). The register $al initially contains an address that we will call Address 1. If we go to Address 1 in memory, we will find another address, which we will call Address 2A. If we go to Address 2A in memory, we will find the ASCII encoding for the first byte of the first string entered in the program arguments.

Checking this option will insert a "delay slot" which makes the next instruction after a branch execute, no matter the outcome of the branch. To avoid having your program behave in unpredictable ways, make sure Delayed branching is turned off. In addition, add a nop instruction after each branch instruction. For example: LI $t1 2 LOOP: ADDI $t0 $t0 1 BLT $to $t1 LOOP NOP # nop added after the branch instruction MIPS Memory Configuration To find the program arguments more easily in memory, you may choose to develop your program using a compact memory configuration (Settings- Memory Configuration) However, your program MUST function properly using the Default memory configuration. You should not run into issues as long as you do not hard-code any memory addresses in your program.
