Evaluation

Evaluation is in the standard format. The source code for the assembler is in the file Simple-Assembler/main.py and SimpleSimulator/simulator.py for the simulator.

To test, change your working directory to automatedTesting and run the evaluator with ./run, or ./run --no-sim if only the assembler is to be evaluated.

Code Documentation

Assembler and Simulator

The assembler and simulator have been made in Python 3.

At the top of the code are definitions for global variables like register to binary conversion which will be used throughout the program.

Then there are utility functions like isvalid in the assembler and isValidImmediate in the simulator which help do certain tasks in the program.

In the main loop of both, different instruction types are handled separately.

Input and Output are always stdin and stdout respectively.

Floating point support

In commit 2557b5, support for the floating point instructions addf, subf and movf was added to the assembler and simulator.

Bonus- Extra instructions

We added the nop instruction as the bonus part.

It has no argument, and it simply does nothing.

Its opcode is 10011.
