Abstract
Official abstract text for this publication.
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) RPl 1 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 D 3010 a indicated by the local read pointer RPl 1 is earlier than positions of descriptors D 3010 b and D 3010 c respectively indicated by local read pointers (second local read pointers) RPl 2 and RPl 3 held by the other data transfer control devices 1062 and 1063.
First claim
Opening claim text (preview).
