  • Publication number: 20250392543
    Abstract: A network device may include packet processing circuitry and memory circuitry accessible by the packet processing circuitry to perform traffic processing operations. The packet processing circuitry may maintain, on the memory circuitry, a flow cache and a fragment mapping table. A leading fragment of an original un-fragmented packet may be used to provide an entry in the flow cache and to provide an entry in the fragment mapping table. The entry in the fragment mapping table and consequently the entry in the flow cache may be used to process one or more non-leading fragments of the original un-fragmented packet.

  • Publication number: 20250271549
    Abstract: At least one example non-transitory machine-readable storage medium includes machine-readable instructions to cause at least one processor circuit to at least set a control voltage of a power amplifier (PA) of a radar circuit based on a bias code. The at least one non-transitory machine-readable storage medium includes machine-readable instructions to cause the at least one processor circuit to cause a power detector of the radar circuit to measure an output power of the PA. The at least one non-transitory machine-readable storage medium includes machine-readable instructions to cause the at least one processor circuit to, based on a rate of change of the bias code with respect to the output power not corresponding to a change in value of the bias code, set the rate of change based on first values of the bias code and second values of the output power.

  • Publication number: 20240422677
    Abstract: A Wi-Fi wake-up receiver that receives wake-up signals encoded using orthogonal frequency division multiplexing based on-off keying (OFDM-OOK) modulation includes receiver circuitry having analog envelope detector circuitry configured to non-linearly down-convert an input signal and provide an energy signal for sampling by an analog-to-digital converter (ADC). A wake-up signal for waking up a main radio in a Wi-Fi device can be based on the digitized energy signal. The receiver circuitry can further include, upstream of the envelope detector circuitry and the ADC in the signal chain, an analog mixer for linearly down-converting the input signal and a low-pass filter for attenuating adjacent-channel interferer (ACI) signals prior to the non-linear down-conversion by the envelope detector circuitry. Sampling of the energy signal rather than the higher-bandwidth input signal yield power savings in the ADC and associated circuitry such as a modem.

  • Patent number: 12063019
    Abstract: An integrated circuit device is provided. In some examples, the integrated circuit device includes an amplifier stage that receives an input signal and a control signal and provides an amplified signal in response. A main path is coupled to the amplifier stage that receives the amplified signal and provides a first feedback signal corresponding to a signal strength of a data-bearing portion of the input signal. A control path also receives the amplified signal and provides a second feedback signal corresponding to a signal strength of the data-bearing portion and an interference component. A gain control circuit is coupled to the main path and the control path that receives the first and second feedback signals and provides the control signal in response to the feedback signals. In some such examples, the control path and main path include separate mixer stages with different performance characteristics.
