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.

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 storage device includes a first interface, an operation circuit, and a nonvolatile memory. The first interface receives a first data chunk from a host device. The operation circuit generates first processed data by processing the first data chunk and generates a first signal indicating a size of the first processed data. The nonvolatile memory stores the first processed data in a storage location, when the storage location at which the first processed data are to be stored is designated to the storage device based on the first signal. The first interface outputs the first signal to the host device.

Abstract: An electronic system includes a host device and a storage device including a first memory device of a volatile type and a second memory device of a nonvolatile type. The first memory device is accessed by the host device through a memory-mapped input-output interface and the second memory device is accessed by the host device through a block accessible interface. The storage device provides a virtual memory region to the host device such that a host-dedicated memory region having a first size included in the first memory device is mapped to the virtual memory region having a second size larger than the first size.
