Platform-agnostic steal-time measurement in a guest operating system
(2018-10)
Report de recerca
Accés obertSteal time is a key performance metric for applications executed in a virtualized environment. Steal time measures the amount of time the processor is preempted by code outside the virtualized environment. This, in turn, ... -
2D error correction for F/F based arrays using in-situ Real-Time Error Detection (RTD)
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Comunicació de congrés
Accés obertThis work proposes in-situ Real-Time Error Detection (RTD): embedding hardware in a memory array for detecting a fault in the array when it occurs, rather than when it is read. RTD breaks the serialization between data ... -
