  • Data transmission system which prefetches data to be transferred
    Patent number: 5388229
    Abstract: In a data transmission device, before the starting of data transmission, a data conduct device detects an external bus, and an address comparator section compares the value of the address signal line with the output values of the parameter memory section. As the result of the comparison, when it is judged that the data to be transmitted is present on the external bus, the address comparator section transmits a write-execution signal to a bus control unit so that the bus control unit writes the data present on the external bus together with the validity bit thereof into the data memory device.
