Abstract: Circuitry arranged for sensing a variable polarity signal comprises an input node supplied with the variable polarity signal to produce an input signal. A first sensing circuit is responsive to the input signal having a first polarity for producing a first signal. A level shifting circuit is responsive to the input signal having a second polarity for shifting a level of the input signal to produce a shifted signal of the first polarity at a level determined by the input signal.

Abstract: A voltage regulator provides a regulated output load voltage at either a positive level or an inverted level relative to an input supply voltage. A switching circuit and control circuit are formed on an integrated circuit having a single pin for coupling to regulator feedback signal. The feedback signal is applied directly to the feedback pin during both positive voltage level regulation and inverted voltage level regulation. The feedback signal may be produced by a feedback circuit comprising an impedance element formed in the integrated circuit.

Abstract: Visualization for active execution tracing pertains an interface used to view, analyze, and manipulate data relating to events leading to a point-of-failure during execution of a function or at least a portion of an application, program, process, or other assemblage of programmable and executable code.

Abstract: Subject matter to regulate real-time data capture rates to match processor-bounded data consumption operations is described. In one aspect, a first transition time for a data source to transition from a first mode to a second mode is determined. A second transition time for the data source to change from the second mode to the first mode is also identified. Based on the first and second transition times, the data source is directed to transition into respective ones of the first and second modes such that real-time capture of data from the data source is regulated by a computing device to match processor-bound data consumption rates of an application consuming the data.

Abstract: Subject matter to regulate real-time data capture rates to match processor-bounded data consumption operations is described. In one aspect, a computing device receives data from a data source at a real time rate. The data is associated with an object of a particular data size. A data transfer buffer of less capacity than the particular data size is filled with the data at the real-time rate. In parallel with filling the data transfer buffer, the data source is transitioned at one or more particular times, to send repeat data. This allows an application to continuously process all data associated with the object independent of a data transfer buffer overflow condition caused by removal of the data from the data transfer buffer at a processor-bounded rate less than the real-time rate.
