DS development > More space for arm7?

#129555 - Noda - Wed May 23, 2007 6:59 pm

Hi,

I guess this question has already been answered by I can't find any thread related to this...

How can I remap the arm7 from the .iwram section to the standard .ewram, so I can have a lot more space for my arm7 binary?

thanks :)

What all is your ARM7 binary doing that would need a lot of space?

.ogg decoding :)

I'm not too familiar with with the full concept of what the DS can do, but couldn't you do the decoding part as part of the ARM9 binary, and use the ARM7 for the actual playback?

Decoding Vorbis on the ARM9 might not be practical. It depends on how much CPU time the other subroutines on the ARM9 are using. For instance, MoonShell DPG video playback decodes audio on the ARM7 to free up ARM9 CPU time for decoding video.
