LMC Evaluator

A Little Minion Computer (edited version of Little Man Computer) Evaluator that helps user test the correctness of the algorithms.

Requirement

1. python 3 runtime
2. lmc assembly code (source code in any format is appreciated)

Usage

In the shell (or cmd), run:

python3 evaluate.py <filename> [start] [end:optional] <task> <tailing_zero>

task: bsc for the basic task testing and adv for the advanced task testing.

tailing_zero: t if the program would output zero (when overflow) and then halt. f if the program would halt directly.

Example

1:

Input:

python3 evaluate.py basicCOMP1071.txt 329 333 bsc f

will take the input from 329 to 333 for the basic task and testing each input.

Output:

2:

Input:

python3 evaluate.py advancedCOMP1071.txt 995 999 adv t

will take the input from 995 to 999 for the advanced task and testing each input.

Output:

Start at: 995
> 995 0
> fetch-execute cycles: 2268

Start at: 996

All test passed!
Total mailboxes used: 42
Average fetch-execute cycles: 5239

PS: I assume that your program will always output the given input whatever it is. For instance, it will output 0 and halt if the input is 0.

PPS: You should not rely on this project as the correctness cannot be ensured. Use it just for fun!
