CPU perfomance...

[jedie]

How many CPU cycles does the 6809 at normal running frequency made in one second?

Currently, unoptimized DragonPy runs around 55000 cycles/sec.

894886.25 (14318180 ÷ 16) - or slightly fewer on some Dragons.

894886.25 when a Dragon is fitted with a 14.31818 MHz crystal. 888625 when a Dragon is fitted with a 14.218 MHz crystal.

Wow. Than i'm far away from that.
But ok, i didn't do any optimizing and have many logging action inserted... there is still a lot air

[jedie]

OK... It has interest me... So i just comment the many logging output with a script:
https://github.com/jedie/DragonPy/commi ... a37f8fce6b

New values are:
* Running is a VirtualBox with PyPy: ~315.000 cycles/sec (before: 140.000 cycles/sec)
* in VM with CPython: ~165.000 cycles/sec (before 37.000 cycles/sec)
* CPython native under Windows: ~235.000 cycles/sec (before 55.000 cycles/sec)

It's still far from 894.000 on a real machine. But i only remove the logging activity and make no real optimizing.
And it's just enough to make some tests...

**update**

Currently TKinter doesn't work with PyPy under Windows. So i have implement a simple console with: https://github.com/jedie/DragonPy/commi ... debcf13f5d

So i can run the sbc09 ROM under Windows with PyPy... And so i go faster than realtime with ~1.370.000 CPU cycles/sec

And remember: I only just commend the few logging activity and not really optimizing code.

You have to take into account that outputting debug data is quite a heavy process, so no wonder that without it, it goes faster...

Congratulations on having it running in real time!
