Software Assisted Hardware Reliability Microsoft Research Even an ideal oracle based hardware technique will need to activate its fail safe mechanism once per emergency. addi tionally, hardware based schemes must ensure that performance gains from operating at a reduced margin outweigh the fail safe penalties. We propose a hardware software collaborative approach to enable aggressive operating margins: a checkpoint recovery mechanism corrects margin violations, while a run time software layer reschedules the program's instruction stream to prevent recurring margin crossings at the same program location.
Software Engineering Hardware Reliability Vs Software Reliability This paper investigates an embedded system that comprises software subsystems and hardware subsystems. in order to more accurately assess the embedded system’s reliability, we proposed a reliability superposition model of the software hardware system with masked data and failure dependency. We demonstrate that a collaborative architecture between hardware and software enables aggressive operating voltage margins, and as a consequence improves processor performance and power efficiency. this co designed architecture is built on the principles of tolerance, avoidance and elimination. Workflow diagram of the proposed software assisted hardware guaranteed approach to deal with emergencies. snapshot of benchmark sieve showing the impact of a pipeline stall due to data. In this paper, probabilistic hw sw interactions, in conjunction with hardware and software reliability, are considered to model and assessment overall hardware software systems reliability.
