PEEK: Heterogeneous Parallelism for Privileged Error Detection in Safety-Critical Processors
Tinglue Wang, Zhenghui Guo, Bing Guo +7
Heterogeneous parallel error detection architecture has been widely studied for safeguarding OoO superscalar processors in safetycritical systems, as it achieves significantly lowe…
From Characterization to Microarchitecture: Designing an Elegant and Reliable BFP-Based NPU
Jie Zhang, Jiapeng Guan, Hao Zhou +4
Block Floating-Point (BFP) is emerging as an attractive data format for edge Neural Processing Units (NPUs), combining wide dynamic range with high hardware efficiency. However, it…
Strix: Re-thinking NPU Reliability from a System Perspective
Jiapeng Guan, Jie Zhang, Hao Zhou +8
DNNs and LLMs increasingly rely on hardware accelerators, including in safety-critical domains, while technology scaling and growing model complexity make hardware faults more freq…
FlexStep: Enabling Flexible Error Detection in Multi/Many-core Real-time Systems
Tinglue Wang, Yiming Li, Wei Tang +6
Reliability and real-time responsiveness in safety-critical systems have traditionally been achieved using error detection mechanisms, such as LockStep, which require pre-configure…
MESC: Re-thinking Algorithmic Priority and/or Criticality Inversions for Heterogeneous MCSs
Jiapeng Guan, Ran Wei, Dean You +4
Modern Mixed-Criticality Systems (MCSs) rely on hardware heterogeneity to satisfy ever-increasing computational demands. However, most of the heterogeneous co-processors are design…
Towards an Extensible Model-Based Digital Twin Framework for Space Launch Vehicles
Ran Wei, Ruizhe Yang, Shijun Liu +6
The concept of Digital Twin (DT) is increasingly applied to systems on different levels of abstraction across domains, to support monitoring, analysis, diagnosis, decision making a…
