Abstract
An apparatus is provided for processing a signal outputted by a sensor installed in a power train control system mounted in a vehicle, the signal indicating an operating state of the power train and formatted in a fixed-point type of data. The apparatus comprises an A/D (analog to digital) converter, a DMA (direct memory access) controller and a transfer unit. The A/D converter converts the signal outputted by the sensor into a signal expressed as fixed-point type of digital data. The DMA controller is equipped with a format converter converting the fixed-point type of digital data to a floating-point type of digital data. The transfer unit transfers the floating-point type of digital data to a memory. The floating-point type of digital data are read out from the memory and subjected to floating-point type of digital processing for controlling the power train.
