The invention discloses an exception recovery method and device for a multi-core heterogeneous system, a chip and electronic equipment. A power management unit of the multi-core heterogeneous system is electrically connected with a first hardware domain and second hardware domains; a first operating system and a second operating system run on the first hardware domain and the second hardware domain respectively; the method comprises the following steps: based on data channels of a first operating system and each second operating system, polling and sending heartbeat signals to each second operating system through the first operating system; determining a target operating system from the second operating systems based on the number of response signals of the second operating systems to the heartbeat signals; and sending a control instruction to the power management unit by using the first operating system, so that the power management unit sends a power-off instruction and a power-on instruction to the target operating system in sequence. When one or more operating systems are abnormal, only the abnormal target operating system is restarted, and other operating systems run normally, so that the use experience of a customer is not influenced.
本申请公开了一种多核异构系统的异常恢复方法、装置、芯片及电子设备,多核异构系统的电源管理单元分别和第一硬件域以及各第二硬件域电连接;第一硬件域和第二硬件域上分别运行第一操作系统和第二操作系统;方法包括基于第一操作系统与各第二操作系统的数据通道,通过第一操作系统向各第二操作系统轮询发送心跳信号;基于各第二操作系统对心跳信号的响应信号的数量,从各第二操作系统中确定目标操作系统;利用第一操作系统向电源管理单元发送控制指令,以使电源管理单元向目标操作系统先后发送下电指令和上电指令。在某一个或多个操作系统发生异常时,仅对发生异常的目标操作系统进行重启,其他操作系统正常运行,不影响客户的使用体验。
