Abstract

This paper presents a task scheduling method for reliable cache architectures (RCAs) of multiprocessor systems. The RCAs dynamically switch their operation modes for reducing the usage of vulnerable SRAMs under real-time constraints. A mixed integer programming model has been built for minimizing vulnerability under real-time constraints. Experimental results have shown that our task scheduling method achieved 47.7--99.9% less vulnerability than a conventional approach.
