But most of all, it's just for the fun of it.
I've been trying to come up with a loose series of "rules" to base this all on with the primary theme being: you have the SPE and 256KB for code/data and nothing else. Without looking at other competitions, I would imagine something along the lines of:
- Each contest is specified as N-way; where N is the number of SPUs you are allowed to use
- LS(s) can be initialized with whatever you like, but once an SPU is started NO communication (except for debugging/status feedback purposes) between the PPU and the SPUs (including mailboxes, etc.) or DMA to/from the SPEs and main/non-LS memory is allowed except SPU-to-SPU transfers via memory-mapped LS and other allowed exceptions
- A framebuffer for visual output is also provided (my inclination is to make this write-only to keep it from being used as working memory)
- Demos, in general, must run at 60 fps
There are probably a lot more things to consider, loop holes to fill, etc. But it captures the essence of my interest in both time and space limitations.
