Abstract
In lieu of a strictly dedicated bus transaction such as a ping and self-identification, the timing delays for an IEEE 1394 serial bus are determined by an asynchronous transaction request and responsive acknowledgement response. Timing may therefore be determined either from asynchronous transactions occurring for other purposes (e.g., a read or write) or initiated for the purpose of determining timing.
