  • Data transfer synchronizing circuit
    Patent number: 4070630
    Abstract: A digital logic circuit synchronizing data transfers between asynchronously clocked data systems. Synchronization is accomplished by three logically interlocked storage elements which respectively record and control (1) the time when data is available for transfer, (2) time when data transfer begins and (3) the time when data transfer is complete. Transfer is accomplished without a loss of data independent of the clock pulse width and frequency relationship of the asynchronously clocked systems.
