METHOD AND APPARATUS FOR TRANSFERRING DATA BETWEEN ASYNCHRONOUS CLOCK DOMAINS |
摘要 |
An invention is provided for transferring data between asynchronous clock domains. The asynchronous clock domains include a source clock domain operating with a source clock signal and a receiving clock domain operating with a receiving clock signal. The invention includes determining a phase shift relationship between the source clock signal and a signal. When the phase shift relationship is below a predetermined threshold the data is transferred between the source clock domain and the receiving clock domain using a first plurality of stage operations. When the phase shift relationship is above the predetermined threshold, the data is transferred between the source clock domain and the receiving clock domain using a second plurality of stage operations that delay data transfer an additional half period of the source clock signal.
