METHOD AND APPARATUS FOR IMPLEMENTING NON-BLOCKING PRIORITY BASED FLOW CONTROL

摘要

An integrated circuit that includes a link controller and a plurality of queue controllers in communication with the link controller is provided. Each of the plurality of queue controllers is operable to be coupled to a dedicated buffer of a remote transmitter of data external to the integrated circuit. The plurality of queue controllers are operable to monitor a buffer full level for the dedicated buffer and each of the plurality of queue controllers are operable to transmit a signal indicating the buffer full level to the link controller. The link controller is operable to transmit a priority flow control signal to the remote transmitter, wherein a time period from transmission of the signal indicating the buffer full level to detection of the buffer full level is consistent for each dedicated buffer.
