Microprocessor load measurement in an embedded system

Embedded systems often use FPGA (Field Programmable Gate Array) chips for their implementation. Soft processors are optimized for their implementation in such circuits. Embedded system processor load is crucial when real-time applications are implemented. Processor load can be analyzed in several ways. The application described in this paper demonstrates a possible method to analyze the processor behavior and a model was developed, which is able to classify processor load. The model was implemented in FPGA without any modification of the original embedded system. The results of the analysis mark the time periods when the processor is overloaded.
