Abstract: Disclosed are methods and apparatus to control data and command flow over a physical communications channel between a transmitter and a receiver, and more specifically to provide a protocol for a point-to-point serial bus architecture with low latency time for flow control and other signaling, regardless of the length of the data packet frame. The abstract data flow control protocol can be employed by various buses as it interacts only with the lowest protocol layers. Separate buffers for data and control can be used to allow the bus to be compatible with slower buses also to support additional control functions without involving a higher protocol layer.
