DMAC -> memset

Brunni · Post by **Brunni** » Sat Dec 31, 2005 8:17 am

Hello,

I use DMAC memcpy with a simple stub, and it's very fast. But now I need a memset routine to quickly zero-initialize large data sections, and I didn't found anything about this on the Internet.

Is there any DMAC accelerated memset routine available, or a way to work directly with DMAC hardware? (for example, the GBA has a src repeat bit for use as a memset, so I think the PSP should also have it ^^)

Thank you in advance for your replies

Could you manually memset the first chunk and then do an overlapping DMAC memcpy to do the rest of the clear/memset?
