Unified error reporting and processing method for multi-chip system

The invention discloses a unified error reporting and processing method for a multi-chip system, which comprises the following steps: step 1, error reporting: a master chip error interrupt controller collects error interrupts of a master chip and a slave chip at the same time, and then triggers a master chip management engine to carry out error interrupt processing; and step 2, error interruption processing: the master chip management engine reads the error information of the master chip error component and the error information of the slave chip error component. Unified error reporting and management of multiple chips are achieved, expenses of system hardware and software are saved, and expandability of different chip numbers is achieved; independent physical signal connection is adopted, channel multiplexing is avoided, and the real-time performance is better; and a single universal pin is adopted for signal connection, so that the cost is lower, and the reliability is higher. 本发明公开了一种多芯片系统的统一错误上报和处理方法，包括如下
