Device for the processing of digital signals coming from optical sensors

A configurable device for processing signals from sensors, comprising:

• at least two assemblies connected to different ones of said sensors, each of said assemblies including:
• n inputs, n being a whole number greater than 1, connected to outputs of said sensors;
• n memories, corresponding to said n inputs, for storing signals corresponding to signals which are output by said sensors;
• a connecting means, arranged between said n inputs and said n memories, for connecting, during a writing of information from said sensors to said n memories, said n inputs to said n memories in a plurality of configurations using at least one switch, a first of said configurations connecting a first one of said n inputs to a first one of said n memories and connecting, using said at least one switch, a second one of said n inputs to a second one of said n memories, and a second of said plurality of configurations connecting said first one of said n inputs to said second one of said n memories, using said at least one switch, wherein one of said plurality of configurations is selected depending on a number of said sensors;
• addressing means, connected to said n memories, for controlling addressing during a reading of and said writing to said n memories;
• and
• combination means, connected to said memories, for combining, during said reading, said signals stored in said n memories and outputting a result of said combining;
• wherein said combination means of a first of said assemblies includes an input for combining an output of said combination means of a second of said assemblies with the signals stored in said n memories of said first of said assemblies.
