Abstract:Abstract-According to the safety-critical Java specification, priority ceiling emulation is a requirement for implementations, as it has preferable properties, such as avoiding priority inversion and being deadlock free on uni-core systems.In this paper we explore our hardware supported implementation of priority ceiling emulation on the multicore Java optimized processor, and compare it to the existing hardware locks on the Java optimized processor.We find that the additional overhead for priority ceiling emu… Show more
