ok, it has been about 2 months released in private beta now I try a public release

here is a little Jaguar GPU Debugger I made to get rid of headaches I had coding on the jaguar gpu ^^
it's far from being complete but it helps debugging the common gpu/dsp code I do, and hopefully will helps you too
the source code are fully included and can be compiled with the free "delphi like" compiler: Lazarus
so you can add any features you want or correct some bugs

Enjoy

GPU Debugger v0.8 beta, source included

Thanks for releasing it !

Thanks for this.

Do you emulate the GPU pipeline also?

About division, how do you emulate 16.16 division?
What is a 16.16 division?
Do you also emulate that the G_REMAIN does not
necessary contain the remainder but a value
that permits to compute the remainder?

read the readme
I don't emulate that, because it would be a bit complicated to represent in the debugger, plus, the debugging process would be fastidious and a bit strange if it was following the exact pipeline.


I don't emulate any of that for the moment

excellent stuff man!

thanks very much for releasing it!

Asshoot... though I commented on this =)

This is just great work man!..
I never got the GPU debugger option to work with my alpine.. so always debugged code in my head.
Now i can use it for something else =)

I hope work on this will be continued it is a verry useful tool.

THANK Y-O-U! Orion & coworkers for beeing the F-I-R-S-T one to release such a Great! tool for the jaguar scene!

/Sym

I know I can hack myself the code

Anyway, it seems that you can emulate the division unit of the GPU/DSP
by doing



For the 16.16 division, it is simply the result of dividing
(a << 16) by b
(48 bits integer for (a << 16))

added the v0.8 of the debugger, with G_REMAIN and other stuffs

I have just tested it. It works even with wine under linux!!

This is really a cool app, thank you Orion!

I found a bug: ADDC is not correctly emulated.

Looking at the source, I think you update the Carry FLAG too early.
(ie before doing the addition !)

thanks, I will take a look at ADDC
I think you can compile it directly for linux because lazarus is multiplatform
maybe you could add a linux version to the distribution

I just quickly tested this morning and I was too lazy to recompile it
but I'll try that.
If I manage to get lazarus working on my PC, I will even try to fix the
problem of ADDC (and probably SUBC too)
