Dynamic thread duplication is a known redundancy technique for multi-cores. The approach duplicates a thread under observation for some time period and compares the signatures of the two threads to detect errors. Hybrid multi-cores, typically implemented on platform FPGAs, enable the unique option of running the thread under observation and its copy in(More)
With ever-decreasing CMOS transistor sizes, integrated circuits are becoming more and more susceptible to errors. A commonly used approach to improve the reliability of digital circuits is triple modular redundancy (TMR). TMR instantiates three copies of a circuit plus additional voter circuits to take majority decisions on the output values. Prior research(More)
The reliability of FPGA based hardware designs is becoming a challenge with future device technologies and, in particular, for avionic and space applications where FPGAs might get exposed to high radiation levels. Typically, redundancy-based techniques are used to achieve fault-tolerant operation. However, hardware redundancy comes with an overhead in(More)
In this paper we present how Intel's Single-Chip-Cloud processor behaves for parallel macro pipeline applications. Subsets of the SCC's available cores can be arranged as a pipeline where each core processes one stage of the overall workload. Each of the independent cores processes a small part of a larger task and feeds the following core with new data(More)
Dynamic thread duplication is a known redundancy technique for multi-cores. Recent research applied this concept to hybrid multi-cores for error detection and introduced thread shadowing that runs hardware threads in the reconfigurable cores and compares their outputs for deviation at configurable signature levels. Previously published work evaluated this(More)
In order to assess the occurrence of blood congestion in the liver during liver resection, we aimed to evaluate the influence of a positive-end-expiratory-pressure (PEEP) and positioning of patients on central venous pressure (CVP) and venous hepatic blood flow parameters. We further analyzed correlations between CVP and venous hepatic blood flow(More)
