Patent ID: 8099537

Claim:
A signal transmission method for communicating between a transmission side and a reception side, the transmission side and the reception side being connected by at least a first transmission line, a second transmission line, and a clock signal transmission line, the signal transmission method comprising: partitioning data into a plurality of data fragments, sending the plurality of data fragments from the transmission side over the first transmission line and the second transmission line, and receiving the plurality of data fragments at the reception side; sending a first clock signal from the reception side to the transmission side over the clock signal transmission line; sending the data fragments from the transmission side to the reception side over the first transmission line and the second transmission line in accordance with the first clock signal; and stopping transmission of the first clock signal from the reception side to the transmission side in order to stop transmission of the data fragments from the transmission side, wherein, after stopping transmission of the first clock signal from the reception side to the transmission side, the reception side (i) transmits to the transmission side an interrupt signal for controlling the transmission side over the first transmission line, and (ii) sends a second clock signal to the transmission side over the second transmission line, wherein the transmission side receives the interrupt signal based on the second clock signal, and wherein each line of the first transmission line, the second transmission line, and the clock signal transmission line is a different line from the other two lines.
