摘要:
A framing mechanism may be provided that enables passing of messages over an addressed bus. This creates a form of information hiding, which passes information by converting an addressed bus interface to a message-based bus interface. Address-based information in a transaction may be replaced with additional information that specifies framing details comprising, for example, a check pattern and length information. The check pattern provides a mechanism for determining whether frame information may be valid. An end device may utilize this length information to determine an actual length of an incoming frame. The combination of the check pattern and the length information may provide a pattern for resynchronizing a data stream when errors are detected. The framing mechanism may operate over existing addressed buses without requiring host side controller hardware modifications and additional host side software driver may be utilized to add the framing information.
