The invention provides a control method and device based on inter-core communication,
electronic equipment and a
chip, and relates to the technical field of computers.The method comprises the steps that power-off is triggered in response to a first subsystem of the
chip, and a second subsystem of the
chip is prevented from sending data to the first subsystem; checking the first subsystem before power-off based on the first state information of the inter-core communication module of the first subsystem and the second state information of the inter-core communication module of the second subsystem; and determining whether the first subsystem is powered off or not according to the check result before power-off. According to the technical scheme provided by the invention, before the first subsystem is powered off, the
data transmission of the opposite-end second subsystem is stopped, and the states of the first subsystem and the second subsystem are checked, so that the problems of unprocessed
data loss caused by direct power-off of the first subsystem and chip
bus hanging caused by
bus access to an invalid address can be avoided, and the reliability of the
system is improved. The power-on and power-off safety in a distributed inter-core communication scene is ensured, and the chip operation stability can be remarkably improved.
