Title:
DATA TRANSFER DEVICE, DATA TRANSMISSION DEVICE, DATA RECEPTION DEVICE, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2010/100730
Kind Code:
A1
Abstract:
A transmission LSI (100) calculates a buffer usage rate based on the data stored in a buffer (101a) of a transmission data processing unit (101) and determines, according to the calculated buffer usage rate, the number of signal lines and their timing on which a phase readjustment will be performed. The transmission LSI (100) and a reception LSI (200) then execute the phase adjustment using part of the signal lines and continue data transfer using the remaining signal lines, thereby continuously maintaining an optimum clock phase without delaying the data transfer.
