LEGv8 Python Emulator

About

This is a tool developed by Spencer Chang at University of Califronia San Diego. It was developed for use in ECE30 in Spring 2020.

It does NOT contain the full LEGv8 Instruction Set, but it does include the main functions that are used in ECE30. I plan to update it if there are functions that we use that were not initially in the set.

I cannot guarantee that successful execution on this platform equates to successful execution on the LEGGIS simulator provided in class.

Usage

From the command-line:

./assembler.py loop_demo_findmax.s -vv -o my_code.out

From another python file:

from assembler import Assembler
if __name__ == '__main__':
    prog = open('my_code.s', 'r')
    a = Assembler(prog)
    a.run()
    print(a)

Unit Testing from another python file: See demo.py

Formatting Data

The format for data is:

.dtype NAME [VALUE]

Right now, the only type supported is .long. [VALUE] is a comma separated list of values. NAME is the case insensitive label given to the address of the data. Example:

.long array 3, 4, 5
.long arraysize 3
