Patent number: 10791514Abstract: In some aspects, the disclosure is directed to methods and systems for NAN tethering a second wireless to a first wireless device. The first wireless device includes a primary processor and a secondary processor. The primary processor negotiates one or more first wake up slots for a NAN service with the second wireless device, establishes the NAN service with the second wireless device, and offloads the NAN service to the secondary processor, responsive to establishing the NAN service and prior to the primary processor entering into a sleep mode. The secondary processor renegotiates one or more second wake up slots with the second wireless device for the offloaded NAN service. The secondary processor is configured to wirelessly tether, the second wireless device to the first wireless device, using the one or more second wake up slots of the offloaded NAN service.Type: GrantFiled: August 22, 2017Date of Patent: September 29, 2020Assignee: Avago Technologies International Sales Pte. LimitedInventors: Sriram Neelakandan, Raghavendra Malladi, Samson Kativarapu, Jagadeesh Cherukuri, Swaraj Vutturi

Patent number: 9760146Abstract: Conditional activation and deactivation of a microprocessor. A hardware portion of an apparatus performs packet processing on received data, where the hardware portion selectively decodes the received data. A microprocessor performs data processing on decoded data, where the microprocessor is conditionally activated for performing the data processing and is conditionally deactivated when not performing the data processing. An output portion receives processed data and audibly renders the processed data without requiring the microprocessor.Type: GrantFiled: January 8, 2007Date of Patent: September 12, 2017Assignee: Imagination Technologies LimitedInventors: Luis Aldaz, Luis Aldaz, Sr., Kaushik Barman, Allan A. Johnson, Raghavendra Malladi

Patent number: 9209988Abstract: A battery-powered WLAN communication device has an activity sensor operable to identify an available packet. A PHY module is awakened to begin receiving the packet. The PHY module decodes a full MAC address from a MAC portion of a header of the packet. A MAC address parser receives the MAC address and determines whether the packet is to be received by comparing the full MAC address to a MAC address of the WLAN communication device. The MAC address parser is awakened to perform the comparing and shutdown after. Packets to be received include beacon packets. A hardware centric MAC separate from the MAC address parser has a beacon processor capable of being awakened from a shutdown state to process a beacon packet. The PHY module, the MAC address parser, and the beacon processor module are operable to be awakened and shutdown independently of each other and of a microprocessor.Type: GrantFiled: August 2, 2012Date of Patent: December 8, 2015Assignee: Imagination Technologies LimitedInventors: Luis Aldaz, Jr., Luis Aldaz, Sr., Kaushik Barman, Allan A.

Patent number: 8811251Abstract: An apparatus comprises a network physical layer and an activity sensor for sensing a packet and activating the network physical layer from shutdown. The network physical layer decodes a PHY header portion and a media access control header portion of a packet header. A MAC has a fixed hardware media access plane implementing IEEE 802.11 series MAC functionality and couples to a microprocessor. A MAC address parser receives the MAC header portion of the packet, for processing the MAC header portion of the packet, and for activating the MAC from a shutdown in response to recognizing a MAC address within the MAC header portion of the packet, such that the MAC is not activated if the MAC parser does not recognize the MAC address, wherein the MAC is operable, after activation, to perform MAC functionality without the microprocessor and to provide data from the packet to the microprocessor.Type: GrantFiled: August 1, 2012Date of Patent: August 19, 2014Assignee: Imagination Technologies, LimitedInventors: Allan A. Johnson, Raghavendra Malladi, Parag Ashok Dighe, Sriram Kankipati, Kaushik Barman, Luis Aldaz, Sr.
