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: 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: Dual gate FD-SOI transistors are used as MOSFET capacitors to replace passive well capacitors in analog microcircuits. Use of the dual gate FD-SOI devices helps to reduce unstable oscillations and improve circuit performance. A thick buried oxide layer within the substrate of an FD-SOI transistor forms a capacitive dielectric that can sustain high operating voltages in the range of 1.2 V-3.3 V, above the transistor threshold voltage. A secondary gate in the FD-SOI transistor is used to create a channel from the back side so that even when the bias voltage on the first gate is small, the effective capacitance remains higher. The capacitance of the buried oxide layer is further utilized as a decoupling capacitor between supply and ground. In one example, a dual gate PMOS FD-SOI transistor is coupled to an operational amplifier and a high voltage output driver to produce a precision-controlled voltage reference generator. In another example, two dual gate PMOS and one dual gate NMOS FD-SOI transistor are coupled to a charge pump, a phase frequency detector, and a current-controlled oscillator to produce a high-performance phase locked loop circuit in which the decoupling capacitor footprint is smaller, in comparison to the conventional usage of passive well capacitance.

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.

Abstract: A method for transmitting data in series includes producing a scrambled signal by applying a scrambling using a pseudo-random sequence to an incoming serial signal conveying the data and producing an outgoing serial signal. The scrambled signal is monitored to detect occurrences of one or more data patterns. In response to the detection of one or more occurrences, one or more actions are taken to protect data in the output signal.
