Abstract: A test circuit measures both the rising edge delay and the falling edge delay associated with a logic cell. The test circuit includes a flip-flop type ring oscillator with two groups of logic cells connected in series in the oscillation path. A first multiplexor switches the ring oscillator between a rising edge and a falling edge mode. A second multiplexer causes the second group of logic cells to be included or excluded from the oscillation path. By measuring the oscillation period in the various modes, the rising edge and falling edge delays can be individually calculated.

Abstract: A source synchronous data transmission system includes a data transmitting device and a data receiving device. A dedicated data line carries a data signal from the data transmission device to the data receiving device. A dedicated clock line carries a modulated clock signal from the data transmission device to the data receiving device. The data transmission device includes a clock data driver configured to encode data into the modulated clock signal by modulating an amplitude of the modulated clock signal. Thus, the clock line of the source synchronous data transmission system carries the clock signal and additional data.

Abstract: An electrostatically actuated oscillating structure includes a first stator subregion, a second stator subregion, a first rotor subregion and a second rotor subregion. Torsional elastic elements mounted to the first and second rotor subregions define an axis of rotation. A mobile element is coupled to the torsional elastic elements. The stator subregions are electrostatically coupled to respective regions of actuation on the mobile element. The stator subregions exhibit an element of structural asymmetry such that the electrostatic coupling surface between the first stator subregion and the first actuation region differs from the electrostatic coupling surface between the second stator subregion and the second actuation region.

Abstract: A stand-alone DC power network is provided with a DC to DC power converter only, and does not have a converter that will convert AC to DC. In addition, each of the different terminals that provides the DC voltage at different levels will be ranked according to priority as to which ones are the most important to supply the full voltage to, and which ones are of secondary importance in the event there is insufficient power in the system to provide full voltage at the specified current for the different loads. A processor monitors the voltage and current at each of the terminals, and in the event a current is attempted to be drawn from the system which would cause a first priority terminal to be reduced in voltage, the processor will instead reduce the power provided to the second priority terminal and ensure that the first priority terminal does not have a significant reduction in the specified voltage or the amount of current supplied to that terminal at the specified voltage.

Abstract: A method, algorithm, architecture, circuit and/or system that compensates for frequency difference in oversampled CDRs. The oversampled CDR uses a programmable divider whose division ratio is changed, for one or more cycles, from its usual division ratio, when accumulated phase movement in either direction exceeds a threshold. Accordingly, the elasticity buffer in oversampled CDRs can be made much smaller or entirely eliminated, resulting in less area, and reduced or eliminated dependence of max allowed burst size on ppm difference. The threshold can be kept programmable, and more than half unit interval, to provide robustness towards high frequency jitter.

Abstract: Various embodiments provide an optimized image filter. The optimized image and video obtains an input image and selects a target pixel for modification. Difference values are then determined between the selected target pixel and each reference pixel of a search area. Subsequently, a weighting function is used to determine weight values for each of the reference pixels of the search area based on their respective difference value. The selected target pixel is then modified by the optimized image filter using the determined weight values. A new target pixel in an apply patch is then selected for modification. The new target pixel is modified using the previously determined weight values reassigned to a new set of reference pixels. The previously determined weight values are reassigned to the new set of reference pixels based on each of the new set of reference pixels' position relative to the new target pixel.
