What is a half-DMA inside the NPU?

[Einstein_rookie_version]

From the reference manue, I can find a term half-DMA, but this term is not well described, and I don't know what this half means, what is the difference bewteen a half-DMA and a normal DMA??? Is it just the size or the available target address is smaller??

Hello @Einstein_rookie_version,

 

Here the term half DMA is used because it's used in only one way (memory to NPU or the other way around, I am confirming it). In any case, this is managed by the aton compiler, you don't have direct access to it.

 

Have a good day,

Julian
