- MBCook 2y agoThat’s why getting DMA right mattered so much.
- maximilianburke 2y agoI'm not quite sure what this means? DMA is the only mechanism that the SPUs had to access memory outside of their local store; it wasn't a matter of getting it right or wrong. Reading RSX memory by SPU DMA wasn't any faster than reading it from the PPU.
- MBCook 2y agoI’m sorry I thought you meant the CPU not the GPU. I didn’t realize DMA didn’t help with GPU memory.
