Abstract:
The invention relates to a peripheral devices connecting system with priority arbitration, comprising at least a connection matrix connected to a plurality of peripheral devices (P1,P2,...,Pn) capable of transmitting a signal to be arbitrated, in particular an interrupt enable signal. The system of this invention comprises first (DCA) and second (DCB) connection matrices which are connected to each other through a plurality of logic gates (PL1,PL2,...,PLn) having a progressive number of inputs, for parallel transmitting a plurality of signals to be arbitrated, in particular interrupt enable signals (IE01,IE02,...,IE0n) issued from the peripheral devices (P1,P2,...,Pn), the first (DCA) and second (DCB) matrices having respective inputs and outputs connected directly to the plurality of peripheral devices (P1,P2,...,Pn). The invention also relates to a special connection matrix for a microcontroller-emulating chip, which includes a peripheral devices connecting system with priority arbitration (1) according to the invention.
