Abstract:
Process for exchanging digital information between electronic cards, characterized in that the electronic cards (CEL) are removably connected on at least one base card (CB) comprising its own individual supply means connected on a printed circuit (CI) possessing a set of tracks (PST) for the flow of electrical signals able to convey the said information, and certain at least of the electrical signals flowing, on this base card, between the connection areas of the electronic cards are amplified (U1-U3) directly on the base card;wherein said set of tracks (PST) forms a hardware support for a digital bus on which are conveyed, synchronously, data logic signals (ADi), address logic signals (ADi), as well as monitoring logic signals, with the exclusion of any clock logic signal; and on the digital bus, all logic signals are conveyed synchronously for using predetermined cycles times for determining the duration of the various processing operations in advance.
