Abstract :
A new digital signal processor (DSP)-based data acquisition system has been designed and installed at the Advanced Photon Source. This system uses a commercial VME-based DSP card to acquire and process X-ray blade signals to determine X-ray beam position for both bending magnet and insertion device beamlines. The system also acquires and processes position data from the narrowband rf BPMs that straddle each insertion device. It is integrated within the storage-ring fast-feedback system and provides filtered data to both the feedback system and the EPICS control system. Features of the system, including analog and digital signal processing, are discussed
