Title:
DATA TRANSFER CONTROL DEVICE AND DATA TRANSFER CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2012/014400
Kind Code:
A1
Abstract:
The data transfer control device of the present invention is capable of improving data transfer efficiency while discarding error data in a DMA transfer which performs error detection for transferred data. In the device, a DMA parameter storing control unit (1112) temporarily stores a plurality of parameters to a store resource; a data processing unit (1201) performs error detection processing for data that is transferred; a DMA parameter return control unit (1122) causes parameters used at transfer time of data for which the processing result in the error detection processing was an error to be returned as parameters for subsequent data transfer use from the store resource; and a completion notification delay control unit (1121), with regard to the plurality of parameters, causes the completion notification to a host system that indicates that data transfer has completed normally for each of the parameters to wait for normal completion of data transfer that uses parameters that had been set earlier than each of the first-mentioned parameters.
