Abstract: A computing system includes a host, a first electronic device connected to the host, and a second electronic device that communicates with the host through the first electronic device. The first electronic device requests a command written in a submission queue of the host based on a doorbell transmitted from the host, stores the command transmitted from the host, requests write data stored in a data buffer of the host, and stores the write data of the data buffer transmitted from the host.

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: An image backup method of a computing system including a host and a memory system includes receiving, by the host, a first image, together with a backup request, performing, by the host, a similarity determination between the first image and images stored in the memory system, based on a first hash function, selectively providing, by the host, the first image to the memory system according to a result of the similarity determination, performing, by the memory system, an identity determination between the first image and the images, based on a second hash function, and providing, by the memory system, the host with information for determining a storage method of the first image according to a result of the identity determination.
