  • Patent number: 12112091
    Abstract: Systems and methods for unifying multiple audio bus interfaces in an audio system are disclosed herein. In one aspect, an integrated circuit (IC) comprises a primary slave audio device comprising a first control circuit, and a dependent slave audio device comprising a second control circuit. The primary slave audio device and the dependent slave audio device are communicatively coupled via a slave status link, and the first control circuit and the second control circuit each configured to receive, from a master audio device, a mode instruction that indicates operation in one of a detach mode and a unify mode. The second control circuit is configured to, while operating in the detach mode, transmit a slave status to the master audio device via a second control lane, and, while operating in the unify mode, transmit the slave status to the primary slave audio device via the slave status link.
    Type: Grant

  • Patent number: 7643486
    Abstract: A pipelined linecard architecture for receiving, modifying, switching, buffering, queuing and dequeuing packets for transmission in a communications network. The linecard has two paths: the receive path, which carries packets into the switch device from the network, and the transmit path, which carries packets from the switch to the network. In the receive path, received packets are processed and switched in a multi-stage pipeline utilizing programmable data structures for fast table lookup and linked list traversal. The pipelined switch operates on several packets in parallel while determining each packet's routing destination. Once that determination is made, each packet is modified to contain new routing information as well as additional header data to help speed it through the switch. Using bandwidth management techniques, each packet is then buffered and enqueued for transmission over the switching fabric to the linecard attached to the proper destination port.
