Abstract: A circuit includes a controller configured to: receive a first decoded beacon frame which includes a first indication of a first data transmission; receive a second decoded beacon frame which includes a second indication of a second data transmission; compare the first and second decoded beacon frames to determine common bytes in the first and second decoded beacon frames; determine an expected time of receiving the common bytes in a third beacon frame; control a device to enter into a low power mode; and control the device to wake up from the low power mode at a time to receive and decode at least a portion of the third beacon frame, in which the time to wake up is based on the expected time to receive the common bytes instead of based on an expected time to receive a preamble at a start of the third beacon frame.

Abstract: In a described example, an integrated circuit includes an input coupled to receive a plurality of beacon frames, the beacon frames include an indication of data transmissions available for a device that includes the integrated circuit. The integrated circuit also includes a controller configured to compare the plurality of beacon frames to determine a plurality of bytes prior to the indication of data transmission available that is present in each of the plurality of beacon frames and is configured to provide a signal indicating a low power mode in which the device does not receive transmissions and to provide a signal indicating a wake mode at a selected time before transmission of the plurality of bytes in a subsequent beacon transmission.

Abstract: Systems and methods disclosed herein receive a network application proxy (NAP)-extended API function call issued by a networking-aware host application. The NAP-extended API function call provides parameter values associated with a host off-loadable packet exchange sequence. Using the parameter values, a NAP module intercepts and responds to one or more incoming network packets associated with the host off-loadable packet exchange sequence while the host processor is in a sleep mode state or is transitioning between sleep mode states.

Abstract: A system and method is disclosed that enables a peripheral or slave device to seamlessly transition in and out of sleep state while remaining completely transparent to host software. When the device is in a sleep mode and incoming data is detected, the device begins a wake-up procedure and data is routed to a first, transitional memory. The size of the transitional memory is selected such that it is capable of buffering data received during time required for the system memory to stabilize from wake-up. Once a second, extended memory is stabilized, the data is buffered from the transitional memory to the extended memory. The device resumes normal operation when its processor has initialized and can read data from the extended memory.
