Abstract: A storage device which is connected to a host using a virtual memory includes a solid state drive that receives a streaming access command including a logical block address (LBA) list and a chunk size, and prefetches stream data requested according to the LBA list and the chunk size from a nonvolatile memory device without an additional command. The prefetched stream data is sequentially loaded onto a buffer, and an in-storage computing block accesses a streaming region registered on the virtual memory to sequentially read the stream data loaded onto the buffer in units of the chunk size. The buffer is mapped onto a virtual memory address of the streaming region.

Abstract: A computing system includes a host, a first electronic device including a memory and an accelerator, and a second electronic device including a direct memory access (DMA) engine. Based on a command transmitted from the host through the first electronic device, the DMA engine transmits data and completion information of the command to the first electronic device. The memory includes a data buffer storing the data and a completion queue buffer storing the completion information. The accelerator executes a calculation on the data. The DMA engine transmits the data to the first electronic device and then transmits the completion information to the first electronic device.
