The Takeaway

The two-stage agent factory approach rediscovers expert-level hardware optimization patterns (like loop fusion and memory restructuring) autonomously. This suggests that scaling agent-based search is a practical path to automating complex High-Level Synthesis (HLS) tasks.

From the abstract

We present an empirical study of how far general-purpose coding agents -- without hardware-specific training -- can optimize hardware designs from high-level algorithmic specifications. We introduce an agent factory, a two-stage pipeline that constructs and coordinates multiple autonomous optimization agents.In Stage~1, the pipeline decomposes a design into sub-kernels, independently optimizes each using pragma and code-level transformations, and formulates an Integer Linear Program (ILP) to ass
