摘要： A system for use in nodes communicating over a CPRI (common public radio interface) allows each networking node in a daisychain configuration to seamlessly manage the control and management HDLC (high-speed data link control) channel for both uplink and downlink. The connection is kept alive through a soft reset flow. Received HDLC packets can be extracted for use by a local node. Locally generated packets can be inserted into the packet data stream at the datalink layer for onward transmission over the CPRI. The system arbitrates between the locally generated packet data held in a buffer in the local node and remote packet data received from a remote node and held in the local node in a first in first out buffer for onward transmission to a subsequent node after arbitration. Remote packet data is given priority.

摘要： New approaches for providing communication between multiple masters (12, 14) and one or more shared resources (24, 30, 100) are needed. One example of a resource that may need to be shared is circuitry complying with the Universal Serial Bus (USB) standard (100). The USB specification defines the use of USB endpoints as data and control channels that reside in a USB device. In some cases it is desirable to have a certain number of endpoints controlled by one processor, and other endpoints controlled by a different processor, thus providing a shared control of all the endpoints. Circuitry (402, 417, 480) may be used to provide steering for additional signals such as interrupts. Other shared resources (24, 30) may use more centralized circuitry (36) to perform a steering function for additional signals.
