Abstract: Systems and methods related to phase-locked loops circuitry and lock-detect circuitry are provided. Some of the systems and methods allow sharing of lock-detect circuitries between multiple phase-locked loops or other suitable circuitry. Others allow multiple circuitries to select from multiple lock-detect circuitries that may use different lock-detect techniques.

Abstract: First and second circuits in an integrated circuit that generate local hot spots are activated at different times in order to reduce heat generation within each of the first and second circuits. The first and second circuits in the integrated circuit have the same circuit architecture. The first circuit processes data during a first time period, and heat generation is reduced in the second circuit during the first time period. A data path of the data is then switched from the first circuit to the second circuit. The second circuit then processes the data during a second time period after the first time period, and heat generation is reduced in the first circuit during the second time period. The data path of the data is then switched from the second circuit back to the first circuit. The first circuit then processes the data again.

Abstract: A method and apparatus for transceiving multiple service data from multiple communication services to a SONET/SDH communication system or network is provided. A SONET/SDH universal framer (SURF) bidirectionally provides communication between a SONET/SDH communication port and multiple service communication ports using their native data format. A provisioning register stores provisioning information describing the communication system and the communication ports. A SONET/SDH byte engine processes complex hierarchical SONET/SDH frames storing intermediate states when it changes to process a byte of data of a different STS-1 equivalent frame in a SONET/SDH STS-N frame. A service byte engine processes the multitude of service data formats and generally its intermediate states are restored, processed, and saved when it changes to process a different data stream or a different frame of data of a given service.

Abstract: The present invention describes a system and method of improving packet forwarding throughput in a router by reducing head of line blocking. In one embodiment of the present invention, incoming packets are stored in a packet reorder buffer. The packets are reordered for forwarding while maintaining the order of packets in a distinct flow. Packets belonging to a distinct flow require to be forwarded in the order that the router receives them. Packets from different flows are reordered such that their forwarding order can be different than the order in which they were received. Packets from the same flow are sent out in the same order as the router receives them.
