PropGCC memory model page?

On the PropGCC memory model matrix page it says there is more information on how the memory models work on the memory model page -- which I can't find. I tried downloading the package and help just pops up a browser to the web docs. It would be nice to have a detailed explanation of how memory is mapped in the various models and how, for example, pages are swapped in and out for non-byte XMM options like SD cards. I could see PropGCC saving me some work building my own development system if certain things work certain ways, but as it is I don't have enough information to tell.

Looks like the memory model link was removed during some pre-beta renovations. We'll add that and other info back. Meanwhile, the memory model page is here: http://propgcc.googlecode.com/hg/doc/Memory.html


XMM codes are always cached via a PASM cache cog. High level documents for xmm caching are TBD*. Meanwhile you can glean the information from the cache drivers.

I recommend starting with cache_interface.spin for a brief spin code interface summary and the skeleton_cache.spin PASM file.

The current drivers are found here: http://code.google.com/p/propgcc/source/browse/#hg%2Floader%2Fspin


*An issue for this TBD has been opened.

Thanks, Jazzed. That clears up some stuff and I realize the drive to get it working goes ahead of documentation.
