    摘要： In accordance with an embodiment of the present invention, an efficient and accurate system and method are described for detecting a fingerprint from swipe sensor system. A swipe sensor module is coupled to a microprocessor module. The swipe sensor module collects fingerprint image data as a plurality of frames and passes the frames of data to the microprocessor module. The microprocessor module assembles the frames of data into a complete image of the fingerprint that is cropped and processed to remove noise and artifacts. The cropped image is used to generate a template in a first instance and to compare an extracted portion of the cropped image to existing templates in a second instance.

    摘要： An apparatus and method for efficient memory utilization in an electronic system comprises a memory divided into memory units of equal size, a data source, and an interface between the memory and the data source, which manages storage and retrieval of data in the memory. The data source generates first data components and second data components, each of the first data components being larger than each of the second data components. Each memory unit is sized to contain one of the second data components. The memory units are configured as a continuous memory ring. The interface stores the data components sequentially in the memory ring as the data components are generated by the data source. The interface also retrieves the data components sequentially from the memory ring. A control module sends control signals to the interface to control read and write operations for the data components.
