[Solved] EE2003 Assignment2- Fibonocci Series

Simple assembly language programming for the RISC-V

## Goals

Demonstrate basic working knowledge of RISC-V assembly

## Given

Test bench assembly code for Fibonacci number Some test cases Template code that you can use to fill in

## Details on the assignment

### Fibonacci series

The Fibonacci series is a well known sequence of numbers that follows the pattern that the *n*th number is the sum of the previous two numbers. This is usually represented in a recursive manner as follows (shown below for Python, similar representations for other languages):

`pythondef fib(n):if (n==1) or (n==2):return 1else:return fib(n-1) + fib(n-2)`

For coding this in Assembly language, you may want to think about how to rewrite this without recursion, since writing recursive programs in Assembly, while not impossible, is not very pleasant.

### Test cases

You are given a test bench that will call a function written by you with different input values. The parameter *n* (number in the sequence to compute) is given in the register `a0`, and you are required to return the computed value also in `a0`. It is up to you how you handle saving intermediate values in your function, or whether you even retain them at all.

## HowTo

Fork this repostiry (`EE2003/a2`) into your namespace so that you can edit and push changes.

The `run.sh` script performs all the steps required to compile and test your code. It assumes the RISCV toolchain is installed in a certain path as set up on the Jupyter server for the course. If you install on your own system you need to make the appropriate settings.

**IMPORTANT**: do not rename files or create new files otherwise the auto-grader will not recognize it. Even if you change the `.drone.yml` file, the system will repeat the tests with different configuration files, and your changes will most likely not be recognized then.

Once you have confirmed that your code passes all the tests, commit all the changes, tag it for submission, and push to your repository.
