  • Dual processors using busy signal for controlling transfer for predetermined length data when receiving processor is processing previously received data
    Patent number: 5019966
    Abstract: A transmitting data processor comprises a data processing unit for supplying a predetermined length of data to be transferred and generating a transfer start signal, and a data transferring unit receiving the predetermined length of data to be transferred from the data processing unit and for transferring the predetermined length of data in a serial form to a receiving data processor. The transmitting data processor also includes a busy detector for detecting a busy signal from the receiving data processor, a register for temporarily holding the transfer start signal from the data processing unit, and a start controller associated to the data transferring unit for causing the data transferring unit to stop the transfer of data during the period the busy signal is active and for allowing the data transferring unit to start the transfer of data when the busy signal becomes inactive after the transfer start signal is generated.
