Abstract: A method and apparatus for signal gain adjustment within an RF integrated circuit (IC) include processing that begins by determining the signal strength of a received RF input signal with respect to a first signal strength scale to produce a signal strength indication. The processing continues by determining whether the signal strength indication exceeds a first high power threshold. If not, the receiver continues to process received RF signals without additional attenuation. If, however, the signal strength indication exceeds the first high power threshold, the received RF input signal is attenuated to produce an attenuated RF input signal. In addition, the first signal strength scale is shifted to produce a shifted signal strength scale. The processing continues by determining whether the signal strength of the attenuated RF input signal exceeds a high power threshold of the shifted signal strength scale or is below a low power threshold of the shifted signal strength scale.

Abstract translation: 用于在RF集成电路（IC）内进行信号增益调整的方法和装置包括通过确定接收到的RF输入信号相对于第一信号强度标度的信号强度开始的处理，以产生信号强度指示。 通过确定信号强度指示是否超过第一高功率阈值来继续处理。 如果不是，则接收机继续处理接收到的RF信号而没有额外的衰减。 然而，如果信号强度指示超过第一高功率阈值，则所接收的RF输入信号被衰减以产生衰减的RF输入信号。 此外，第一信号强度标度被移位以产生移位的信号强度标尺。 该处理通过确定衰减的RF输入信号的信号强度是否超过移位的信号强度标度的高功率阈值或低于移位的信号强度标度的低功率阈值来继续。

Abstract: A cache is coupled to receive an access which includes a cache allocate indication. If the access is a miss in the cache, the cache either allocates a cache block storage location to store the cache block addressed by the access or does not allocate a cache block storage location in response to the cache allocate indication. In one implementation, the cache is coupled to an interconnect with one or more agents. In such an implementation, the cache accesses may be performed in response to transactions on the interconnect, and the transactions include the cache allocate indication. Thus, the source of a cache access specifies whether or not to allocate a cache block storage location in response to a miss by the cache access. The source may use a variety of mechanisms for generating the cache allocate indication.

Abstract: A feedforward equalizer for equalizing a sequence of signal samples received by a receiver from a remote transmitter. The feedforward equalizer has a gain and is included in the receiver which includes a timing recovery module for setting a sampling phase and a decoder. The feedforward equalizer comprises a non-adaptive filter and a gain stage. The non-adaptive filter receives the signal samples and produces a filtered signal. The gain stage adjusts the gain of the feedforward equalizer by adjusting the amplitude of the filtered signal. The amplitude of the filtered signal is adjusted so that it fits in the operational range of the decoder. The feedforward equalizer does not affect the sampling phase setting of the timing recovery module of the receiver.

Abstract: Certain aspects of a method and system for tuning an antenna using injection may include mixing a received DVB-H signal with a reference oscillator signal to generate an added DVB-H signal. A mixed signal may be generated from the added DVB-H signal using the reference oscillator signal. A wireless antenna that receives the received DVB-H signal may be tuned based on a received signal strength indicator (RSSI) associated with the mixed signal. The reference oscillator signal may be generated and then may be amplified. The first mixed DVB-H signal may be amplified prior to the generating of the mixed signal. The RSSI associated with the mixed signal may be determined. The tuning may occur during receiving of a preamble of a packet for the received DVB-H signal and/or during receiving of a plurality of packets for the received DVB-H signal.
