Multiple DSP system for real time parallel processing and feedback control on fusion experiments

This paper describes a specially designed system for real time parallel processing and feedback control on fusion experiments. The system is being implemented in PCI and VME modules, based on an array of four synchronizable DSPs, with 1 Mbyte of global RAM, 12 bits resolution, four analog inputs with sampling frequency up to 40 MSPS, two analog or waveform generator outputs with an update rate up to 100 MSPS, eight digital opto-coupled inputs/outputs and one external global trigger optical input. The user interface appears as a virtual instrument from LabView for Windows.
