摘要

Disclosed is a data transfer control device (1061) provided with a read pointer update unit (5004) for updating the value of a global read pointer (RPg) with the value of a local read pointer (RPl1) if, when completion of data transfer has been recognized, the readout order of a descriptor (D3010a), indicated by a local read pointer (first local read pointer) (RPl1) which is held by a local read pointer holding unit (5007), is in front of the readout orders of descriptors (D3010b, D3010c) indicated by local read pointers (second local read pointers) (RPl2 and RPl3) which are held by other data transfer control devices (1062 and 1063).
