Abstract
A data transfer control device 1061 includes a read pointer update unit 5004 updating a value of a global read pointer RPg with a value of a local read pointer (first local read pointer) RPl1 held by a local read pointer hold unit 5007 when completion of data transfer is recognized and a position, in an order of reading descriptors, of a descriptor D3010a indicated by the local read pointer RPl1 is earlier than positions of descriptors D3010b and D3010c respectively indicated by local read pointers (second local read pointers) RPl2 and RPl3 held by the other data transfer control devices 1062 and 1063.
