Rapid parallel interruption detection circuit suitable for multi-sensor system

The invention relates to an interrupt detection circuit, in particular to a quick parallel interrupt detection circuit suitable for a multi-sensor system. The system comprises combinational logic which is used for receiving interrupt signals sent by all sensors, combining the interrupt signals into a single interrupt combination signal and outputting the single interrupt combination signal to a host. The device is characterized by further comprising a plurality of storage units and a communication control module. The storage units are electrically connected with the sensors in a one-to-one correspondence manner, and the storage units are used for storing interrupt signals sent by the corresponding sensors. The communication control module is used for converting a serial reading instruction sent by the host into a parallel reading signal, reading interrupt signals stored in all the storage units, controlling the storage units to release the memory after reading, converting read parallel data into serial data a
