Structure-augmented LLMs for High-Level Synthesis Pragma Optimization

Pragma insertion drives the quality of high-level synthesis (HLS) designs. Choosing the right directives demands expert knowledge and reasoning about loop nesting, data dependences, and memory layout. While existing large language models (LLMs) show promise in code generation, they lack explicit program-structure aware...

LowRank-SSM: Hardware-Software Co-Design for Rank-Reduced Mamba Acceleration on FPGA

LowRank-SSM is a hardware-software co-design framework that decomposes the input and output projection weights via post-training truncated SVD and introduces a greedy bandwise rank-allocation algorithm that searches for the per-band rank vector that minimizes weight storage while respecting a user-specified accuracy co...
