PURPOSE:To transmit much more information by comparing a transmission address code with a transmission source code with a memory to improve other processing capability of a CPU. CONSTITUTION:The memory address of a receiving data D1 is designated and outputted by a received code address at a memory 1 and by a transmission code address at a memory 2. When the data D1 is a data to be transmitted to the receiver, since a specific data is writed in an address of the memory 1 designated by the transmitted address code of the data D1, whether the data is to be transmitted or not is discriminated by checking the output data. The transmission source is discriminated by checking the output data of the memory 2 similarly. The outputs of the memories 1, 2 are gated by an OR gate 4 at the same time, both the outputs are compared and selected at an AND gate 5, outputted as one-bit information D2 and processed by the CPU. Thus, the comparison between the transmission address code and transmission source code is attained by the hardware. |
