# Assignment1: RISC-V Assembly and Instruction Pipeline
( Due: Sep 16, 2019 )

## Requirements
1. Following the instructions of [Lab1: R32I Simulator](/@sysprog/H1TpVYMdB), you shall write RISC-V assembly programs (R32I ISA) such as calculating Fibonacci numbers and output to the console with system calls.
* Don't implement the same subject as others do. Your program shall be different.
* You have to ensure the program functioned with [Ripes](https://github.com/mortbopet/Ripes) simulator.
2. You have to explain how each instruction works along with [Ripes](https://github.com/mortbopet/Ripes) simulator.
* Explain your program with the visualization for multiplexer input selection, register write/enable signals and more. You have to illustrate each stage such as IF, ID, IE, MEM, and WB. In addition, you should discuss the steps of memory updates accordingly.
3. Write down your thoughts and progress in [HackMD notes](https://hackmd.io/s/features).
* [Example page](https://hackmd.io/@kksweet8845/2019q3homworkquiz2): Do not modify this note.
* Insert your HackMD notes and RISC-V assembly programs in the following table.
