Abstract: A clock source selector for selecting either a first clock signal A or a second clock signal B in accordance with a switch request signal includes three retiming circuits each consisting of two clocked flip-flops. The switch request signal is first retimed relative to clock A to give a signal P, is then retimed relative to clock B to give a signal Q, and finally is retimed relative to clock A to give a signal R. Selector circuitry operates such that when signal Q is asserted, the second clock signal B is output, when neither signal P nor signal R, as combined by a NOR gate, are asserted, the first clock signal A is output, and at other times a zero level is output. The clock source selector can be used in an integrated circuit to form a glitch-free multiplexer.

Abstract: A pinned-photodiode image sensor using shared output amplifiers, for example output amplifiers in the 2.5T arrangement has transfer gate control lines alternating or cross-coupled between successive columns or adjacent rows. This assists in removing row-row mismatches. In preferred embodiments, the approach is applied to Bayer pattern RGB sensors, and allows the gain and/or the exposure of green pixels to be controlled separately from those of red and blue pixels.

Abstract: A method is described for identifying an inaccurate model of a hardware circuit. The method includes the steps of simulating the model of the circuit by applying a plurality of signals, said plurality of signals having at least one abstract data type level to provide a set of expected results, replacing the at least one abstract data type level with two or more levels having different values to thereby provide and expanded set of signals to apply to said model, resimulating the model with said expanded set and comparing the two sets of results and providing an output signal indicating if the model is inaccurate if the results contradict.

Abstract: A semiconductor integrated circuit for the processing of conditional access television signals comprises an input interface for receiving encrypted television signals and an output interface for output of decrypted television signals. Control signals broadcast with the television signals include control words and common keys. Entitlement messages are received in encrypted form, encrypted according to a secret key unique to each semiconductor integrated circuit. The input interface is connected to a decryption circuit whereby the only manner of providing the common keys to the circuit are in encrypted form encrypted according to the secret key. Due to the monolithic nature of the circuit, no secrets are exposed and the system is secure. Alternatively, the entitlement messages are encrypted for decryption with the common keys and a unique ID stored in the circuit is compared with an ID in a received entitlement message. Only if the received and stored IDs match can the rights be stored and used.

Abstract: Lighting flicker in the output of a video imaging device is detected. The video imaging device has a main picture area divided into pixels for producing successive images at a frame rate. A series of signals are produced from at least one additional picture area adjacent the main picture area, with the additional picture area having a size substantially larger than a pixel. Each of the signals is a function of light incident on the additional picture area in a time period substantially shorter than that of the frame rate. A predetermined number of the signals are accumulated to form a series of compound samples, and the compound samples are filtered to detect components indicating the lighting flicker. The filtering is performed using a bandpass filter tuned to the nominal flicker frequency. The compound samples are formed at a sample rate which is a multiple of the nominal flicker frequency, and the filtering is performed by taking the fundamental output component of a radix-N butterfly.
