Arbitration techniques for a high speed serial bus

摘要：

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.

摘要（中）：

一种提高串行总线效率的方法和装置。通过减少强制的分工差距来提高总线效率可以通过将子操作（EOS）令牌的显式结束附加到作为子操作的最后一个数据包的数据包来实现。 EOS应被选择为不容易与用于正常数据编码的编码混淆的编码。 EOS令牌的存在允许仲裁开始，而不必在总线上看到EOS令牌之后等待分工差距。此外，它允许通过与包含EOS令牌的数据包连接来进行飞行。在某些情况下，可能会有多个连接。由于EOS令牌独立于子操作类型，因此随着新的子动作的开发，这种技术随着扩展。采用整体总线效能的特点可以增加。
