  • Method and apparatus for isochronous data transfer with retry capability
    Patent number: 6717947
    Abstract: Isochronous data transfers guarantee data packets are received at a particular frequency and within a prespecified jitter-tolerance. Asynchronous data transfers guarantee data integrity by allowing missed or errant packets to be resent as many times as needed until an error-free packet may be reconstructed at the receiver. Isochronous transfers address real-time needs but do not address the data integrity issue. Asynchronous transfers address the data integrity issue but cannot guarantee error-free data packets will be available so as to meet a real-time constraint. The present invention provides method and apparatus enable isochronous data transfers with improved data integrity. Various link layer and transaction layer mechanisms are taught. An embodiment involving the IEEE 1394 bus specification is addressed in detail.
