Patent number: 10880884Abstract: Various methods and systems are provided for space, frequency and time domain coexistence of RF signals. In one example, among others, a communication device includes a coexistence manager capable of monitoring operating conditions of a cellular modem and a coexistence assistant capable of monitoring operating conditions of a wireless connectivity unit. The coexistence manager is capable of modifying operation of the modem and/or unit based on an operating condition change. In another example, a method includes detecting a change in antenna isolation and/or operating temperature of a FE filter, determining filtering characteristics of the FE filter based at least in part upon the change, and modifying communications of coexisting communication protocols based at least in part upon the filtering characteristics. In another example, a TX/RX configuration for coexisting communication protocols is determined and communications in a protocol is modified based at least in part upon the TX/RX configuration.Type: GrantFiled: October 17, 2017Date of Patent: December 29, 2020Assignee: AVAGO TECHNOLOGIES INTERNATIONAL SALES PTE.

Patent number: 10839118Abstract: A circuit design is partitioned into a plurality of partitions during a first synthesis by a computer processor. After modification of the circuit design, the computer processor determines changed partitions and unchanged partitions of the circuit design. The computer processor then determines dependent partitions of the changed partitions. The changed partitions and the dependent partitions are re-synthesized by the computer processor into respective re-synthesized partitions, and the computer processor then combines the respective re-synthesized partitions and the unchanged partitions into a complete synthesized circuit design in a memory.Type: GrantFiled: November 29, 2018Date of Patent: November 17, 2020Assignee: Xilinx, Inc.Inventors: Kameshwar Chandrasekar, Aman Gayasen, Manpreet Singh, Surya Pratik Saha, Sanjay Saha

Publication number: 20120314693Abstract: Embodiments for processing client traffic in a wireless device operated in hotspot mode are provided. Embodiments enable downlink and uplink client traffic flows within the wireless device that reduce the load on the application processor (AP) of the wireless device. In an embodiment, client traffic flows bypass the AP entirely allowing the AP to enter a power saving mode during hotspot sessions. This results in increased battery lifetime and reduced power consumption of the wireless device. In addition, the hotspot session quality is improved by the reduced latency resulting from bypassing the AP.Type: ApplicationFiled: May 23, 2012Publication date: December 13, 2012Applicant: Broadcom CorporationInventors: Kamesh Medapalli, Sanjay Saha
