Patent ID: 7843503

Claim:
A device for reading information in at least one set of electronic components connected to a communication bus in order to send said information over said communication bus, said device including: a sensor for reading values held in at least some of said electronic components holding a value to be sent and an arbiter circuit for successively sending the read values over said communication bus, wherein when the electronic components are arranged in one set, the arbiter circuit includes at least one plurality of processing blocks allocated respectively to each of said electronic components, and when the electronic components are arranged in a plurality of sets, the arbiter circuit includes at least one plurality of processing blocks allocated to each of said sets of electronic components, and wherein the processing blocks of each of said plurality of processing blocks are arranged such that, in the course of a transmission of the said values, said processing blocks transfer from one block to a following block of said plurality of processing blocks a unique authorization signal for the transmission of the read value, said authorization signal being capable, when passing from one processing block to the following block, of detecting those among said one set of electronic components or plurality of sets of electronic components associated with said plurality of processing blocks which have an item of information to transmit and of causing, where applicable, the successive transmission of said information to said communication bus.
