This paper presents a novel VLSI approach for combustion engine control. The approach is based on a real time solution of a thermodynamical differential equation. The control system calculates an optimum ignition point by fast measurement and real time processing of signals as temperature, pressure and volume of the combustion chamber. The required computational power cannot be met with standard signal processors. We present the design of a mechatronic system that is based on an application specific vector architecture. The optimization of the algorithm and the dataformat, the mapping on an architecture, the physical design of the VLSI chip set, the test results, and the system integration are shown.
