It’s at this point that you might reach for the magic of direct memory access (DMA). [Larry] is here to advocate for its use. DMA isn’t just for the embedded world; it was once a big deal on ...

DMA (Direct Memory Access) frees the CPU from these menial tasks. With DMA, peripheral devices do not have to ask the CPU to fetch some data for them, but can do it themselves. Unfortunately ...

Direct Memory Access (DMA) is a crucial feature in computer systems that significantly enhances data transfer efficiency. If you’ve ever wondered how your system manages to handle large data transfers ...

Very simple example showing how to use Agrona library buffers to share data with native code via direct memory access. Unless you use some more complicated stuff (e.g: callbacks from native code which ...

In our last example, we allocated memory simply, but as we saw the direct memory access (DMA) engine requires that our buffers be aligned to 4 KiB pages boundaries. If the buffers are not so aligned, ...

Tutorials at the IEEE Hot Chips Conference ... CXL 3.0 also enables multi-level switching and memory fabrics and peer-to-peer direct memory access. The presentation also outlined how CXL enables ...
