PURPOSE:To realize an effective and high-speed data transmittance by installing a port sequencer and a daisy chain controller and setting a sequence setting means necessary for the said port sequencer. CONSTITUTION:A bypass is installed consisting of an input port having a input data bus and a input control line, and a output port having a output data bus and a output control line, and a bypass line route is installed consisting of a bypass gate 107, etc. which bypasses a signal of the said input data bus to the said output data bus. Port sequencers 102, 122 and a daisy chain controller 120 are installed to be operated respectively by the signals of the said input control line and the said output control line, and the daisy transfer line as input or output. And, in order to set a transfer function sequence required for the said port sequencer, data processing modules having sequence setting means are cascaded plurally. Thus the daisy chain transmitting of data among plural data processing modules is carried out, resulting in an effective and high-speed data transmittance. |
