  Introduction
The TRACE32 Multitask Debugger is an adaptive debugger, which allows debugging on target systems using realtime kernels. The debugger is fully integrated in the User Interface of the Emulator. It allows the display of kernel resources, manual execution of system calls, task selective debugging and many sophisticated real time analysis functions. The analysis functions include symbolic system call trace and detailed performance analysis functions.

The configuration to different multitask kernels is controlled by a special macro language. By changing this macro definition the user may adapt the debugger to nearly any multitask kernel. Standard configurations are available for the most used multitask kernels. The macro language can also be used to define user specific windows for any kind of special data structures. The supported features vary between different kernels. Not all features are supported for all processors and kernels.
