Abstract: In order to increase the speed of a computation process using an accelerator, an accelerator control device 1 is provided with a generation unit 12 and a control unit 14. The generation unit 12 generates a directed acyclic graph (DAG) representing the process flow based on a computer program to be executed. If data corresponding to a DAG node is stored in a memory provided in an accelerator to be controlled, the control unit 14 controls the accelerator so as to execute a process corresponding to an edge of the DAG using the data stored in the memory of the accelerator.

Abstract: To speed up processing for decoding a source packet from a coded packet based on rateless coding, a terminal is provided with: a storage unit which holds a matrix with n rows and n columns and an n-bit flag; and a calculation unit which performs processing for extracting an element that becomes 1 in both a received n-bit coded packet and the flag, and performing processing for performing an exclusive OR operation of a row vector of the matrix that corresponds to the element number of the extracted element and the received coded packet on all extracted elements, determines an element that is the first to become 1 in the coded packet after the exclusive OR operation, and inserts, into the matrix, the coded packet after the exclusive OR operation as a row vector corresponding to the element number of the determined element.
