It takes strips of equal sizes from one memory, and puts them with differentspacings or strides somewhere else. Is that what you think of ?Not really. It would help for the case of DMA from/to the GPU, but not for all the 2D rendering case you could do on the CPU.
Could you write an elaborate document about it, like a sort of report ? I'm confused again and a few diagrams will help me :-) yg ************************************************************* To unsubscribe, send an e-mail to majordomo@xxxxxxxx with unsubscribe f-cpu in the body. http://f-cpu.seul.org/
