Abstract: A package comprising a substrate comprising at least one dielectric layer and a plurality of interconnects; a first integrated device coupled to the substrate through a first plurality of solder interconnects, wherein the first plurality of solder interconnects includes a first plurality of inner solder interconnects and a first plurality of perimeter solder interconnects; and a second integrated device coupled to the substrate through a second plurality of solder interconnects. The first integrated device is configured to be electrically coupled to the second integrated device through an electrical path. The electrical path comprises an inner solder interconnect from the first plurality of inner solder interconnects, at least one interconnect from the plurality of interconnects, and a solder interconnect from the second plurality of solder interconnects.

Abstract: A method for providing low latency frequency switching includes operating a first processing component on a first die and operating a second processing component on a second die with the same first clock signal having a first frequency. A request to switch the first frequency to a second, new frequency is received and a second clock signal having the second, new frequency is produced. Data flow between the first die and second die may be stopped. And then the second clock signal is transmitted to a dual phased locked loop architecture on a die interface. A PCLK signal is created from the combined first and second clock signals and an NCLK signal is created from the second clock signal. Next, the PCLK signal is divided and aligned with the NCLK signal. Once the PCLK signal is aligned with the NCLK signal, data flow is resumed between the two dies.

Abstract: A method comprising: sensing an ambient temperature at an electronic apparatus; and switching between a first processing mode of the electronic apparatus and a second processing mode of the electronic device, in response to an increase in the ambient temperature above a threshold.

Abstract: Apparatus and method are described for selecting for subsequent use an antenna from a plurality of antennas. The selection is biased in favor of the antenna most likely to receive subsequent signals having best signal quality. In a preferred embodiment the signal quality comprises received signal strength.

Abstract: Antenna selection control apparatus for a diversity antenna system including at least two antennas. The received power strength is measured from a selected antenna and compared with a reference power level. The reference power level is adjusted depending upon the signal to noise ratio of received signals, and if the selected antenna falls below the adjusted threshold another antenna is selected.

Abstract: A received and demodulated multi-level signal (32) is corrected for D.C. offset by a feedback loop (34) which applies a correction signal (38) to the multi-level signal (32). Initial coarse correction is provided by feeding the corrected signal (42) into the feedback loop where a low pass filter (36) averages the corrected signal over time and detects departure from zero of this time-averaged signal. After initial coarse correction, finer correction of D.C. offset is provided in a data-aided mode in which detected data values (46) are fed into the feedback loop (34). The method achieves D.C. offset correction without the need to know anything about the data pattern of the received signal (32).
