Abstract: A video image capturing and displaying system and related method is disclosed. The system includes an imaging module for capturing a video image consisting of a time series of image frames, each image frame comprising a plurality of sequential lines of pixels; a video image compressing module, comprising at least a first compressing engine and a second compressing engine, for compressing the captured video image; a control unit for actuating one of at least the first compressing engine and the second compressing engine for compressing each specific sequential line; a video image decompressing module for decompressing the compressed video image corresponding to the compressing engine; a first buffer for storing the decompressed video image which is not displayed in time; and a display for displaying the video image based on the stored video image and the decompressed video image.

Abstract: A data management method for a USB device includes the steps of: sampling an analog input signal, and generating digital sample data corresponding to samples of the analog input signal; monitoring the number of the digital sample data generated within a predefined time interval; if the number of the digital sample data generated at the end of the predefined time interval matches a predetermined value, providing the digital sample data to a USB host; and if the number of the digital sample data generated at the end of the predefined time interval does not match the predetermined value, processing the digital sample data such that the number of the processed digital sample data matches the predetermined value, and providing the processed digital sample data to the USB host. A USB device including a data management module for implementing the data management method is also disclosed.

Abstract: A data synchronizer system includes at least two synchronizers for receiving a source pulse signal, a corresponding source clock, and a destination clock. At least two first memory units each have a destination clock input. A first switch has an input coupled to the source pulse signal and an output selectively coupled to a source pulse signal input of any one of the synchronizers. A second memory unit has an input coupled to the source data signal and a clock input coupled to the source clock. A second switch has an input coupled to an output of the second memory unit and an output selectively coupled to an input of any one of the first memory units. A generator is coupled to outputs of the synchronizers for outputting a data switch signal. A multiplexer has inputs coupled to outputs of the first memory units and outputs a destination data signal.

Abstract: A multi-pipe synchronizer system includes at least two synchronizers for receiving a source signal and corresponding source clock, and a destination clock. A switch is coupled to an input of each synchronizer for coupling the source signal to a selected synchronizer. A generator is coupled to an output of each synchronizer. The generator is for merging output of the synchronizers into a destination signal corresponding to the destination clock.

Abstract: A method for establishing communication between a USB having a first memory device and a second memory device and a host includes reading first USB identification data stored in the first memory device, determining if the USB device can communicate with the host based on the first USB identification data, and reading second USB identification data stored in the second memory device for establishing communication between the USB device and the host if the USB device cannot communicate with the host based on the first USB identification data.
