A signal processing device includes an interface, which includes a demodulation processing unit that executes demodulation processing, a processing unit that executes demux processing or the like, and a sync signal line, a valid signal line, a clock signal line, and a data signal line disposed between the demodulation processing unit and the processing unit, that transmits data signals as two-bit parallel transmission.

In one embodiment, updating and searching of entries in a hardware content-addressable memory is coordinated to provide more searching bandwidth (e.g., for determining packet processing information), including, but not limited to, when vectors are moved among entries to free up desired entry positions for insertion of other vectors. A lookup operation is performed in content-addressable memory entries in a hardware content-addressable memory based on a lookup word to generate a content-addressable memory lookup result. Typically overlapping in time, a matching operation is performed in one or more transitory entries to generate a transitory matching result based on the lookup word. These transitory entries are populated with transitory vectors and have an associated index within the content-addressable memory, with these transitory vectors are subsequently inserted in the content-addressable memory at their associated index positions. A matching result is determined from the content-addressable memory lookup result and the transitory matching result.

Techniques and devices for service-specific tagging of data by an application processor (AP) of a user equipment device (UE). A first indication may be sent from the UE to a baseband processor (BB) of the UE of one or more quality of service preferences for an upcoming data session, and the BB may configure one or more layers of the BB according to the quality of service preferences. The BB may further communicate with a network to establish protocols for the quality of service preferences. The BB may determine one or more network conditions, and may transmit feedback from the BB to the AP related to the determined network conditions. In response, the AP may send a second indication of one or more updated quality of service preferences to the BB based at least in part on the feedback received from the BB.

A network device determines that a frame priority of a received frame is a value corresponding to an audio video bridging (AVB) communication protocol. When the network device determines that a destination address of the frame is not included in a database having network addresses, the network device prevents the frame from being transmitted according to the AVB communication protocol, including either (i) dropping the frame, or (ii) transmitting the frame only from a first set of one or more ports of the network device according to a communication protocol that is different than the AVB communication protocol. When the network device determines that the frame is permitted to be transmitted according to the AVB communication protocol, the network device transmits the frame from a second set of one or more ports according to the AVB communication protocol.

A network device determines that a frame priority of a received frame is a value corresponding to an audio video bridging (AVB) communication protocol. When the network device determines that a destination address of the frame is not included in a forwarding database, the network device prevents the frame from being enqueued in any of one or more egress queues of the network device that are reserved for packets to be transmitted via the AVB communication protocol. When the network device determines, based on determining that the destination address is included in the forwarding database, that the frame is permitted to be enqueued in one of the one or more egress queues reserved for frames that are to be transmitted according to the AVB communication protocol, the network device enqueues the frame in one of the one or more egress queues for transmission via the AVB communication protocol.
