The use of COTS-based systems in space missions for scientific data processing is very attractive, as their ratio of performance to power consumption of commercial components can be an order of magnitude greater than that of radiation hardened components, and the price differential is even higher.
This paper presents an experimental evaluation of a software-implemented fault tolerance environment built around a set of self-checking ARMOR proceses running on different machines that provide error detection and recovery services to themselves and to spaceborne scientific applications.
We present a technique for minimizing the power dissipated in a VLSI chip by lowering the operating voltage without any significant penalty in the chip throughput even though low voltage operation results in slower circuits.
