Abstract
Embodiments of a local interface unit are disclosed that may allow for managing credits and tokens as part of flow control method. The local interface unit may include a transmit unit and a receive unit. The transmit unit may be configured to receive credits and tokens, determine an available number of credits based on the number received tokens, determine an available number of tokens based on the number of received tokens, and send the available credits to an arbitration unit. The available credits may then be updated, by the transmit unit in response to receiving a selected transaction from the arbitration, and the transmit unit may then transmit the selected transaction, and update the available credits and the available tokens once the transaction has been sent. The receive unit may be configured to send credits and tokens to a transmit unit, and receive a transaction sent by a transmit unit.
