Abstract: A computational storage device includes an interface exchanging a signal with a first external source, a non-volatile memory device, a storage controller, a device memory, and a computation engine. The interface receives an indirect usage request instructing the computation engine to perform a second computation for second input data from a second external source while performing a first computation for first input data acquired from the first external source. The computation engine provides the first input data and first intermediate data generated when performing the first computation to an external computational storage device in response to the indirect usage request, requests the first computation from the external computational storage device, performs the second computation for the second input data loaded from the non-volatile memory device to the device memory, and outputs second result data generated by completing the second computation to the second external source through the interface.

Abstract: A storage device includes a memory device that stores data, a storage controller that stores a data stream including plural frames in the memory device based on a write request from a host, and a scaler that generates a mapping table in which, for each frame, one or more logical addresses assigned to the frame is mapped to a frame number assigned to the frame. For each frame included in the data stream, the scaler performs an operation of obtaining the one or more logical addresses assigned to the frame by referring to the mapping table and providing a batch read request to the storage controller to read all the one or more logical addresses assigned to the frame. The storage controller controls the memory device to perform a read operation on a memory area corresponding to the one or more logical addresses based on the batch read request.
