Abstract

Many of the benefits of Java, including its inherentportability, networking support and simplicity, are ofincreasing importance to large-scale distributed real-timeembedded (DRE) systems, but have beenunavailable due to the lack of acceptable real-timeperformance. Recent work establishing the Real-TimeSpecification for Java (RTSJ) [i] has led to theemergence of associated Real-Time Java VirtualMachines (RT JVMs) which promise to bridge this gap.This paper describes benchmarking results on a RT JVMin a uni-processing environment, and compares them toboth C++ implementations of similar behavior andapplication requirements associated with large-scaleavionics systems. This paper extends previouslypublished results [ii][iii] by including avionicsapplication level tests.
