A first feature of a data processing system is in that, in a data transfer path including a plurality of signal lines used for data transfer, a phase control is performed independently for each of the signal lines. A second feature is in that data is selectively transferred from a coupling exchange to a signal processor or a signal memory. A third feature is in that the signal processor, the signal memory and the coupling exchange are coupled to each other. By the features, the phase margin in the transfer data and clocks is widened and high speed transfer can be realized. Since data can be directly written in the signal memory, the signal processor can be efficiently used. Further, efficiency in processing and transfer of signals is improved.
