Device managing accessing priority to common resources, of functional modules divided over a plurality of local units in each of which they form of local daisy chain

摘要

The device embodying the invention comprises a plurality of functional modules divided over a plurality of local units in each of which they form a local daisy chain, said local units being interconnected so as to form an external daisy chain, and each comprising a coupling module enabling propagation of a local daisy chain towards the external daisy chain and vice versa. The invention relates notably to the interconnection of plural trays each containing a limited number of instrumentation modules or boards.
