Abstract
A method and apparatus of improving serial bus efficiency. Improvement of bus efficiency through the reduction of enforced subaction gaps can be accomplished by attaching an explicit end of subaction (EOS) token to packets that are the last packet of a subaction. The EOS should be selected to be an encoding that is not easily confused with any encoding used for normal data encoding. The presence of the EOS token permits arbitration to begin without waiting for a subaction gap after the EOS token is seen on the bus. Additionally, it permits fly by concatenation with packets containing an EOS token. In some cases multiple concatenations are possible. Because the EOS token is independent of subaction type, this technique expands readily as new subactions are developed. Employing the features overall bus efficiency can be increased.
