Load-Adaptive Monitor-Driven Hardware for Preventing Embedded Real-Time Systems from Overloads Caused by Excessive Interrupt Rates

In the paper, a concept and an early analysis of an embedded hardware/software
architecture designed to prevent the software from both timing disturbances and
interrupt overloads is outlined. The architecture is composed of an FPGA (MCU)
used to run the hardware (software) part of an embedded 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 software load being monitored
with no intrusion to the software. According to the actual software load it is
able to buffer all interrupts and related data while the software is highly
loaded and redirect the interrupts to the MCU as soon as the software becomes
underloaded.
