Hardwareaufwand vermieden und eine Integration in einem einzigen SensorAuswertechip ermöglicht wird. In der vorliegenden Arbeit wird ein Prozessor vorgestellt, der auf diese Interpolationsaufgabe zugeschnitten ist. Die Korrektheit des Entwurfs wird durch eine Implementierung in einem programmierbaren Logikbaustein nachgewiesen, als Kennfeldspeicher dient dabei ein externes EPROM. Der beschriebene Logik-Entwurf kann für die Integration in einem SensorAuswertechip übernommen werden.In conventional sensory systems, mechanical and electronical components are generally operating at seperated locations. Intelligent sensors integrate mechanical and electronical elements to a single system, thus offering new facilities for a common error compensation. A well known method applicable to a wide range of sensor types is to calculate the corrected measurement value by interpolating a sensor correction function represented by a two dimensional characteristic diagram. A processor dedicated for this interpolation task can save a lot of hardware resources and computation time compared with a solution applying a standard microcontroller. The dedicated processor requires only little chip area if it is integrated into the signal processing chip. In the following, the logic design for a dedicated interpolation processor is described.The functionality was verified first by an implementation in a programmable logic device, whereby the characteristic diagram was stored in an external EPROM. The processor design is applicable for an integrated signal processing circuit.
