<p>PROBLEM TO BE SOLVED: To realize synchronous transfer between devices without connecting the clock of a high frequency on a data transfer route and to improve transfer speed and reliability by transmitting a data signal and the phase adjusting signal of a clock to the data transfer route between a transmission device and a reception device. SOLUTION: When the transmission device 1 transfers data to the reception device 2, the transmission device 1 being a transmission side loads data on the data bus 5 of the transfer route 3 in synchronism with the phase adjusting signal 4 generated inside. The reception device 2 being a reception side executes a take-in processing on data on the data bus 5 in synchronism with the phase adjusting signal 4. In such a case, the frequency of the phase adjusting signal 4 depends on the transfer data length (data 1, data 2,... data N) of the transmission device being the transmission side. Thus, high speed data transfer between the devices 1 and 2 can be realized without transmitting the clock of the high frequency on the data transfer route 3.</p> |
