# CO M21 Assignment

Repository of group 10101102 for Computer Organization, Monsoon 2021 semester, assignment at IIITD.

## About the repository

- This repository contains an Assembler `Simple-Assembler` and a simulator `SimpleSimulator`.

- The assembler converts a given code (pertaining to the ISA, refer to `Assignment.pdf`) to it's binary equivalent. It is also capable of reporting descriptive errors with the line number. (Also the error is colored 😄)

- The simulator processes such binaries and dumps the program counter and the registers while the program is running, and after an `hlt` instruction, it dumps the state of the memory. It is important to note that we follow a Von-Neumann Architecture (unified memory | Instruction memory, hlt, followed by variables). It also plots the graph of memory access per cycle and is not capable of handling exceptions.

- `automated-testing` is a testing suite designed to testify the correctness of outputs from the `assembler` and `simulator`. It contains the traces, binaries and a few assembly codes.

- `SimpleSimulator/plots/` contain all the plots generated by the simulator according to the timestamp (since epoch).

## How to evaluate

* Go to the `automatedTesting` directory and execute the `run` file with appropiate options passed as arguments.

* Options available for automated testing:

	1. `--verbose`: Prints verbose output

	2. `--no-asm`: Does not evaluate the assembler

	3. `--no-sim`: Does not evaluate the simulator

## How to run only the assembler or the simulator

- Change directory to `Simple-Assembler` or `SimpleSimulator`.

- Use `./run` (on bash) and enter your assembly code or binary, after entering add a newline and press `ctrl+D` to terminate stdin. 

- Alternatively, you can directly run `asm.py` or `samuelator.py`.
