The goal of this diploma thesis is an object oriented real time microkernel for Intel´s 32-Bit microcontroller 80960.
The code is written in Oberon-2 using the crosscompiler for the i960 developed by Richard Hable at the FIM. This crosscompiler should be tested for its reliability and efficiency while programming the microkernel in question.
As a basis a microkernel for the 8086 was used that had been written by Richard Fanta in C++.
After having ported the given C++ code to Oberon-2 and onto the i960 the problem of switching between processes was solved and a real time scheduling mechanism was implemented (preemptive and priority driven).
Using this microkernel now it is possible to develop real time applications in a high level language and bring in the advantages of parallelism into conventional programs. A clear programming interface provides access to the functionality of the kernel.
