<p>PURPOSE:To accelerate the transfer speed of data, by providing a second storage circuit in a transmission side and a reception side, respectively, other than a first storage circuit, and writing the data on the storage circuit on the other side while the storage circuit on one side transfers the data, in a data communication system which takes synchronization by using the storage circuit. CONSTITUTION:First of all, in an initial cycle, the data is written on a MEM1 that is a first storage circuit at the transmission side. In the next cycle, the data in the MEM1 is read out, and is transferred to the reception side. At the reception side, transferred data is written on a MEM3 that is the first storage circuit at the reception side. During that time, at the transmission side, the next data is written on a MEM2 that is the second storage circuit at the transmission side. In the cycle after next, at the reception side, the data written on the MEM3 is read out, and simultaneously, the data written on the MEM2 at the transmission side, and is transferred to the reception side, and it is written on a MEM4 that is the second storage circuit at the reception side. During that time, the next data is written on the MEM1. Hereafter, such operation is repeated. The same operation is performed in a MEM circuit 2.</p> |
