2. Determine the delay engine and high-performance IPC technology to realize the natural smoothness of the system. HarmonyOS OS solves the problem of insufficient performance of the existing system by using deterministic delay engine and high-performance IPC. The delay engine can assign the priority and time limit of task execution in the system so that it can be scheduled before task execution. Task resources with high priority will be scheduled first, and the application response delay will be reduced by 25.7%. The compact structure of HarmonyOS system microkernel greatly improves the performance of IPC, and the efficiency of process communication is five times higher than that of existing systems.
3. Rebuild the credibility and security of terminal equipment based on microkernel architecture. HarmonyOS operating system adopts a brand-new microkernel design, which has stronger security features and low latency. The basic idea of microkernel design is to simplify kernel functions, realize system services in user mode outside the kernel as much as possible, and increase mutual security protection. Microkernel only provides the most basic services, such as multi-process scheduling and multi-process communication.
