A completely useless use of silicon. The fastest way of copying memory block is to offload it to DMA or some other dedicated hardware. Using CPU to copy blocks

A completely useless use of silicon. The fastest way of copying memory block is to offload it to DMA or some other dedicated hardware. Using CPU to copy blocks is just a stall. And please, do not call ARM a RISC!
- branson2 5y agoDMA is cache oblivious, so you will have to clear all CPU caches before every memcpy. Very bad idea.
