Abstract
According to one example embodiment, a direct memory access (DMA) engine and buffer is disclosed. The vector buffer may be explicitly programmable, and may include advanced logic for reordering non-unity-stride vector data. An example MEMCPY instruction may provide an access request to the DMA buffer, which may then service the request asynchronously. Bitwise guards are set over memory in use, and cleared as each bit is read.
