Module d'acquisition analogique parallèle pour un système multiprocesseur

Abstract

In this paper an analogue data acquisition device, which is multiprocessor oriente, is described; using parallel transfer structures and direct access in private memories, the system involves a specific analogue-to-digital converter. The design and operation of the system are optimized so as to increase the acquisition rate for various numbers of channels and word lengths. One of the processors leads the conversion and interfaces, without reducing the availability of the other processors. The prototype of the device has been working in a hybrid simulation computer with the predicted efficiency.
