  • Patent number: 9100917
    Abstract: A system-on-chip including a host interface module configured to interface the system-on-chip to a host processor of a wireless device and to communicate with the host processor of the wireless device via a bus. The bus uses an application programming interface of the system-on-chip. The host processor uses the application programming interface to configure a power save mode of the system-on-chip. A power management module operated the system-on-chip in the power save mode without performing a handshake with the host processor via the bus in response to the host processor stopping communication with the system-on-chip. The handshake includes (i) sending a request to enter the power save mode to the host processor via the bus and (ii) receiving an acknowledgement of the request from the host processor via the bus.

  • Patent number: 8041317
    Abstract: A system includes a radio frequency transceiver. A baseband processor includes an automatic gain control module. The automatic gain control module has a gain that changes from and subsequently returns to a predetermined value each time the radio frequency transceiver receives a radio frequency signal. The baseband processor is configured to selectively generate an interrupt signal each time a radio frequency signal is received based on a magnitude of the change in the gain of the automatic gain control module and a length of time in which the gain returns to the predetermined value. A control module is configured to identify a radio frequency signal received by the radio frequency transceiver as a radar signal in response to the baseband processor having generated a plurality of interrupt signals at substantially equal time intervals.
