Abstract
A memory access control device has a memory control unit and a software execution unit executing software. The memory control unit has: a data transmission unit configured to perform multicast transfer that reads a data from the memory and transmits the data to data transfer destinations through a network; a data reception unit configured to receive multicast transfer data from the network; and a reception data counter configured to indicate a number of multicast transfer data received by the data reception unit. The software execution unit instructs the memory control unit to perform a plurality of multicast transfers and then reads respective reception data counters of the data transfer destinations for each checkpoint in sequence of the software to determine completion of the plurality of multicast transfers.
