Pulse processing architectures

This paper introduces and discusses the features of a new multiprocessor architecture that aims at performing digital pulse processing at high throughput rates. It is based on a master Digital Signal Processor (DSP), special purpose trigger pulse locator and data routing circuits and an expandable array of slave peripheral DSPs. An historical perspective about the evolution of pulse spectrometry systems over the last 40 years is given. It is recognized that, up to the very recent commercial outcome of digital pulse processing systems, a tremendous evolution of technology but little change in their basic architecture has occurred.
