I haven't been able to work on it much over the past couple of weeks because of midterms. Perhaps I can work on it some more next week. The main problems I'm facing is horrendously slow emulation speed (32 instructions per second vs 6 million instructions per second) and strange quirks when loading large ROMs from storage memory.

...and, without trying to be excessively discouraging, I have a feel that won't get much better... unless there's some giant bug preventing things from running faster and that once fixed it jumps to a much higher speed.

Yeah, that's a pretty significant difference. With that said, though, I don't understand how C on a 60MHz processor could possibly be emulating 32 instructions per second. That just seems too horrifically low.

I'm afraid I'm going to have to drop this in its current state. I have too many things to tend to in school/real life, and I'm barely able to work on any of my projects. The code is under a GPL license on GitHub, so feel free to try to get it in a working state. Right now, the two key problems are loading large ROM files (200KB+) and emulator speed.

I'm rather disappointed to hear this, Souvik. Sad

I hope that it becomes feasible for you or someone else to pick this up in the near future and solve whatever is making it so dreadfully slow.

If I ever figure out how to use the SH7724's cache, you might be able to speed up emulation a lot by:

Running speed-critical code from the cache (flash runs at a low speed on the peripheral clock, cache runs at the cpu clock)
Directly access the ROM from the flash chip. All flash writes should just use BFile calls.
You have more than 128KB of RAM available, so no blocks there

I am trying to compile the code that you have, but it keeps giving me this:

Code:

make: Interrupt/Exception caught (code = 0xc00000fd, addr = 0x4227d3)


make: *** [build] Error 255

That seems to be a bug in make, not with my makefile/code. Try downloading a different version.

A different version of the SDK? Or just the make? I have 0.3 and I'm pretty sure the new version isn't out yet.

Yeah, pWabbit definitely won't compile under PrizmSDK 0.3. You need the latest version of libfxcg (https://github.com/Jonimoose/libfxcg).

Just remove the #include menu.hpp from pWabbit.c, or get the new file from my git repository. I forgot to add menu.hpp to git, so it didn't upload, but it shouldn't matter because I didn't use the menu system anyway.

But 187,500 times faster to get even 6MHz? I find it hard to believe there isn't some massive time sink that's being overlooked here. I've be very interested to see some examination of the codebase running under Tari's "emulation" system.

That's not very helpful. Razz

Surely there are other lines that have the word "error" in them.
