Abstract

The paper details design of a hardware unit for preventing real-time systems from overloads caused by excessive interrupt rates. Novelty of the hardware can be seen in the fact it is able to adapt interrupt service rate to the RT system load and to the actual priority assignment policy. The load is monitored on basis of special low-overhead signals produced by the system for this purpose. The hardware is designed to preprocess all interrupts before they arrive to the system. The hardware is ready to buffer each interrupt-related communication until the system is underloaded or running an activity having a lower priority comparing to the interrupt. Design of the hardware was described in VHDL and synthesized into Xilinx Spartan-6 devices. Details such as buiding blocks, overheads and limits related to the realization are presented in this paper.
