Sometimes those blocks are used in microcontrollers to copy large swathes of data inside RAM. A less exotic example of this we can mention are Intel Xeon platforms. I interpreted this as a reference to the Data Streaming Accelerator (DSA) [1], which is a programmable DMA peripheral on the SoC that can be used to accelerate writes to and from I/O devices (amongst other things).
