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