ABSTRACT:
In a multiprocessor machine comprising K channels of different signals, the signals are converted to digital samples by K analog-to-digital converters connected respectively to each channel. N monolithic elementary processors are connected by means of a sample acquisition bus which is common to all of the K analog-to-digital converters. They are also connected by a ring bus which is common to all of the processors so as to permit circulation between processors of the results of computation performed on the samples received by each processor. A control unit and at least one transfer automat synchronized by a common clock signal initiate respectively on the one hand the performance of computations to be carried out by the processors on the samples which they receive as well as on the other hand the transfer of samples on the acquisition bus and the transfer of the results of computation between processors on the ring bus.
