For the detection of defects in pipelines a dual core DSP FPGA multiprocessor system for data acquisition and reduction of a measuring system based on ultrasonic sensors has been developed. During the pipeline inspection no communication to the outside world exists, the accumulated data have to be stored on a mass storage device. The amount of data for a 250 kilometre run is in the range of about 15 000 TBytes at a rate of up to 68 GByte/s. This amount of data has to be filtered, reduced and compressed by a factor of 150 000 to store it on a robust storage device. To overcome these difficulties a massive parallel multiprocessing system with FPGAs and dual core DSPs has been developed. The communication and the data transfer between the several units and components are done via serial and parallel interfaces. The complete computing power is installed in a volume of half a shoe box.
