Abstract:
The invention relates to procedures and methods for administering and transferring data within multi-dimensional systems consisting of transmitters and receivers. The division of a data stream into several independent branches and the subsequent combination sequential collection of the individual branches to form a data stream can be carried out in a simple manner. The individual data streams are re-combined in a correct time sequence. Said inventive method is particularly useful for processing re-entrant codes and is suitable for configurable architectures wherein efficient control of the configuration and reconfiguration is highly important.

Abstract:
A fingerprint sensing circuit, system, and method is disclosed. The fingerprint sensor maybe include a plurality of inputs coupled to a plurality of fingerprint sensing electrodes and to an analog front end. The analog front end may be configured to generate at least one digital value in response to a capacitance of at least one of the plurality of fingerprint sensing electrodes. Additionally, the analog front end may include a quadrature demodulation circuit to generate at least one demodulated value for processing by a channel engine. The channel engine may generate a capacitance result value that is based, in part, on the demodulated value and is stored in a memory.
