Structure of μT-Kernel 3.0

%utk 3.0 consists of "%utk/OS" that handles the intrinsic functions of RTOS such as task scheduling, synchronization, and communication between tasks, "%utk/SM" that offers additional system management functions, and "%utk/DS" that offers functions for software debugger. The position and structure of μT-Kernel 3.0 is shown in Figure 1.

μT-Kernel/OS provides the following functions:

• Task Management Functions

• Task Synchronization Functions

• Task Exception Handling Functions

• Synchronization and Communication Functions

• Extended Synchronization and Communication Functions

• Memory Pool Management Functions

• Time Management Functions

• Interrupt Management Functions

• System Management Functions

• Subsystem Management Functions

μT-Kernel/SM provides the following kinds of functions:

• System Memory Management Functions

• Device Management Functions

• Interrupt Management Functions

• I/O Port Access Support Functions

• Power Management Functions

• System Configuration Information Management Functions

• Memory Cache Control Functions

• Physical Timer Functions

• Utility Functions

μT-Kernel/DS provides the following kinds of functions exclusively for debugging use:

• Kernel Internal State Acquisition Functions

• Trace Functions
