Title:
METHOD AND DEVICE FOR TRANSFERRING DATA TO PERIPHERAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2006/054618
Kind Code:
A1
Abstract:
A host device (2) has a transfer function (22) for dividing output data into a plurality of sets of transfer data and transferring them to a peripheral device (3). The transfer function (22) provides a device for successively compressing the plurality of sets of transfer data, storing them in a memory (14), selecting a compressed data set (82c) and a non-compressed data set (82n), and transferring them. The transfer function (22) makes judgments including the following judgments. When a current data set transfer can be started and if the current data set has been compressed, the compressed data set is transferred. If the current data set has not be compressed, the first end time when the compressed data set is transferred and the second end time when the non-compressed data set is transferred are predicted and the data set having the shorter end time predicted is transferred. If the next data set compression is not started when transfer is started, the compression of the data set is started.
