Abstract

The embodiment of the invention provides an inter-process communication method and device, an Internet of Things operating system and Internet of Things equipment, and the method comprises the steps: switching a first process from a user mode to a kernel mode when the first process calls a second process in the user mode; determining a target service code corresponding to the second process in the user space of the user mode; copying the target service code into a kernel space of the kernel mode; and when the target service code is executed in the kernel mode to obtain service result data, switching the first process from the kernel mode to the user mode, so that the first process obtains the service result data in the user mode. According to the embodiment of the invention, the occupation of system memory resources is reduced, and the inter-process communication efficiency is improved.
