HEARS: High-Fidelity Emulation for Aging Fault via Scan-Chain Reuse and Flip-Flop Sampling

As semiconductor nodes shrink to 7nm and below, aging-induced delay faults (e.g., NBTI, HCI) increasingly threaten SoC reliability. To optimize resilience, designers require early-stage evaluation of fault impacts; however, traditional Fault Injection (FI) assessments are either bottlenecked by the slow execution of pr...

RapidGEMM: An Efficient Tile-agnostic GEMM for Mixture-of-Experts Training

Grouped GEMM (General Matrix Multiplication) is the core primitive in performing each expert’s matrix multiplications on tokens routed to them in MoE (Mixture-of-Experts) training. However, existing implementations either drop tokens or zero-pad each expert’s token slice to meet GEMM tiling and alignment requirements....

From Passive Retrieval to Active Memory Navigation: Learning to Use Memory as a Structured Action Space

NapMem is introduced, a framework for learning to use long-term user memory as a structured action space rather than passively retrieved context, and suggests that long-term user memory benefits from coupling structured storage with a learned policy for using memory at the appropriate granularity.
