摘要：An apparatus is provided for processing a signal outputted by a sensor installedin 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 apparatuscomprises an A/D (analog to digital) converter, a DMA (direct memory access) controllerand a transfer unit. The A/D converter converts the signal outputted by the sensor into asignal expressed as fixed-point type of digital data. The DMA controller is equipped witha format converter converting the fixed-point type of digital data to a floating-point typeof digital data. The transfer unit transfers the floating-point type of digital data to amemory. The floating-point type of digital data are read out from the memory andsubjected to floating-point type of digital processing for controlling the power train.
