Phoenix is a fault-tolerantreal-time network-attachedstorage device (NASD). Like other NASD architectures, Phoenix provides an object-based interface to data stored on network-att...
We present the concept of alternative functionality for improving dependability in distributed embedded systems. Alternative functionality is a mechanism that complements traditio...
—Fault tolerance (FT) has become a major concern in computing systems. Instruction duplication has been proposed to verify application execution at run time. Two techniques, inst...
Under current worst-case design practices, manufacturers specify conservative values for processor frequencies in order to guarantee correctness. To recover some of the lost perfo...
