MC6809 CPU emulator written in Python
Project description
MC6809 CPU emulator written in Python
MC6809 is a Open source (GPL v3 or later) emulator for the legendary 6809 CPU, used in 30 years old homecomputer Dragon 32 and Tandy TRS-80 Color Computer (CoCo)…
Tested with Python 2.7, 3.4 and PyPy
A example usage can be find in: MC6809/example6809.py
There is a simple benchmark. Run e.g.:
~$ MC6809 benchmark --help # run benchmark with default settings: ~$ MC6809 benchmark # run with own settings: ~$ MC6809 benchmark --loops 10 --multiply 20
(MC6809 is the cli installed by setup.py)
tests
We use nose to run the tests, e.g.:
~$ cd MC6809 ~/MC6809 $ python2 setup.py nosetests ~/MC6809 $ python3 setup.py nosetests
profile
To profile, e.g.:
~$ python -m cProfile -s cumulative MC6809 benchmark
TODO
Update ‘cpu6809_html_debug.py’
Use bottle for http control server part
unimplemented OPs:
RESET
SWI / SWI2 / SWI3
SYNC
