Investigation of transient faults on JOP processor

This paper investigates the effect and propagation of transient faults on JOP (Java Optimized Processor). JOP processor is intended for applications of embedded real-time systems and the primary implementation technology is in an FPGA. The investigation is based on 4350 transient faults which are injected in the processor using simulation-based fault injection method. The effect and propagation of the faults on different parts of this processor are observed and evaluated. Based on the experimental results, bytecode cache and bytecode memory are two sensible parts in the processor, since about 100 percent of injected faults have affected them. The results show that between 81% and 85% of injected faults cause processor failure and between 12% and 14% of non-failing faults are overwritten.
