what is this conversion function ? if you have img[x][y], you want something like img[x/64][y/64][x%64][y%64] it's not the good example because you need the size, but that's the idea.
Here, you're just mixing address lines. Nothing crazy. CÃdric's example seems to work at the byte level with a more complicated pattern, that's where SIMD is helpful to shuffle the bytes. ************************************************************* To unsubscribe, send an e-mail to majordomo@xxxxxxxx with unsubscribe f-cpu in the body. http://f-cpu.seul.org/
