PURPOSE:To attain flexible data transfer by writing connection between processing blocks in a control block. CONSTITUTION:A processor P writes the relation (connecting relation) of transmission/reception between the processing blocks PB1-PBn in the control block CB. The CB receives the data to be processed successivey from the P, and when a reception request signal is inputted from a previously specified processing block (PB1 e.g.) through a reception request line RR, the CB outputs an address indicating the CB to a transmission address bus TA, the address of the PB1 to be received to a reception address bus RA, the data to be transferred to a data line D, and a strobing signal to a strobing line ST. On the other hand, the PB1 outputs the RR, and when the self-address and a strobing signal are outputted to the RA and the ST, respectively, the PB1 receives data from the D. Subsequently, the PB1 executes the processing charged to itself, and after completing the processing, outputs a transmission request line TR. When receiving the request, the CB transfers the data to the bus to be received which has been previously applied from the P. |
