Microprocessor Aided Data Acquisition at VEDAS

Three microprocessor systems have been developed to support data acquisition in nuclear physics multiparameter experiments. A bit-slice processor accumulates up to 256 1-dim spectra and 16 2-dim spectra. A microprocessor, based on the AM 29116 ALU, performes a fast consistency check on the coincidence data. A VME-Bus double-processor displays a colored scatterplot.
