SemanticBBV: A Semantic Signature for Cross-Program Knowledge Reuse in Microarchitecture Simulation
Zhenguo Liu, Chengao Shi, Chen Ding +1
For decades, sampling-based techniques have been the de facto standard for accelerating microarchitecture simulation, with the Basic Block Vector (BBV) serving as the cornerstone p…
