Hi there.

I read an article about copying data using CPU ("for" loop) and DMA (Mem2Mem).

Below in the comments of that article is described also an approach, which uses memcpy() function. Interestingly, this is also (much) faster than DMA. I never used memcpy() function, so I would like to ask, how could it be faster than DMA? As long as it is a function, I suppose it occupy CPU? But how it works? Where can I see its definition?
