Abstract

In the paper, a concept and an early analysis of an HW/SW architecture designed to prevent the SW from both timing disturbances and interrupt overloads is outlined. The architecture is composed of an FPGA (MCU) used to run the HW (SW) part of an application. Comparing to previous approaches, novelty of the architecture can be seen in the fact it is able to adapt interrupt service rates to the actual SW load being monitored with no intrusion to the SW. According to the actual SW load it is able to buffer all interrupts and related data while the SW is highly loaded or redirect the interrupts to the MCU as soon as the SW becomes underloaded.
