Abstract :
The article presents three different implementations of a traditional real-time kernel in hardware. All approaches improved performance and determinism by several orders of magnitude when compared with software-based real time kernels. The first implementation provides an integrated deterministic CPU and a deterministic and high performance multitasking real time kernel in hardware. The second implementation provides a deterministic and high performance standalone multitasking real time kernel in hardware and the last implementation provides a deterministic and high performance real time kernel for homogeneous and heterogeneous multiprocessor real-time systems
