Introduction to RISC-V Assembly Programming

Code due Wed Feb 21st by 11:59pm in your Lab03 GitHub repo

Links

Tests: https://github.com/USF-CS631-S24/tests

Autograder: https://github.com/phpeterson-usf/autograder

Requirements

1. You will develop RISC-V assembly language implementations of the following problems. You will be given the C implementations, you need to write the RISC-V implementations.
2. Your executable must be compiled with a Makefile
3. Before you add files to your repo, do a $ make clean so you don’t add/commit build products like executables or .o files
4. We will test the labs using autograder

add4: Adds four 32-bit integers together and returns the result. Example:

$ ./add4 1 2 3 4
C: 10
Asm: 10

quadratic: Runs the quadratic equation (ax^2 + bx + c) on the 32-bit integers x, a, b, c and returns the result. Example:

$ ./quadratic 4 3 2 1
C: 57
Asm: 57

min: Calculates the smaller of two 32-bit integers and returns its value. Example:

$ ./min 2 3
C: 2
Asm: 2

findmax Finds the maximum integer in an array.

$ ./findmax 1 2 99 4 5
C: 99
Asm: 99

Given

The Lab03 GitHub repo will contain starter code including a Makefile, the C versions of the functions above, and empty .s files for you to fill in.

Rubric

1. Your lab will receive the score indicated by the autograder
2. To get the test cases, git pull in the tests repo
