    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.

    Abstract translation: 本发明涉及连接具有优先级仲裁系统的外围设备，至少包括：连接到外围设备的多个连接矩阵（P1，P2，...，Pn）的能够发送的信号的被仲裁，特别是中断 使能信号。 本发明的系统包括通过逻辑门的多个（PL1，PL2，...，PLN），其具有的输入端渐进数目，发射并联连接的第一海誓山盟（DCA）和第二（DCB）连接矩阵 的信号的多个来进行仲裁，在特定的中断使能信号（IE01，IE02，...，IE0n）从所述外围装置（P1，P2，...，Pn）的，发出第（DCA）和第二（DCB ）矩阵具有直接连接至外围设备（P1，P2，...，Pn）的的多元性respectivement输入和输出。 因此本发明涉及一种用于微控制器的模拟芯片，其包括连接系统具有优先级仲裁（1）gemäß本发明的外围设备特殊的连接矩阵。
