- LibOS: Make the application isolated from the hardware, simplify the difficulty and complexity of the application to access the hardware.
- BatchOS： Isolate applications from the operating system to strengthen system security and improve execution efficiency.
- Multiprog & Time-sharing OS: Share CPU resource between multiply applications.
- Address Space OS: Isolate the memory address space accessed by the application, limit the mutual interference between the application, and improve security.
- Process OS: Allows application dynamically creates new process and enhance process management and resource management capabilities.
- Filesystem OS：Allows applications to store data persistently.
- IPC OS：Allows multiple apps to interact with data and event notifications between processes.
- Thread & Coroutine OS：Implement threading and coroutine applications to simplify switching and data sharing.
- SyncMutex OS：Supports synchronous and exclusive access to shared resources in multithreaded applications.
- Device OS：Improve the I/O efficiency and human-computer interaction ability of the application, and support serial ports/block devices/keyboards/mice/display devices based on peripheral interrupts.
