发明名称 Method and apparatus for accelerating detection of serial bus device speed signals
摘要 A method and apparatus for accelerating detection of speed code signals, and in particular S400 signals, for IEEE Standard 1394-1995 serial bus devices. The present invention validates S400 mode immediately after detecting an S400 speed signal, or immediately after detecting an S400 speed signal following a first S200 speed signal. The invention further provides S200 and S100 mode validation according to current implementations. Additionally, the invention does not require RX_DATA_PREFIX as a pre-requisite for signal detection.
