LLM-Guided Strategy Synthesis for Scalable Equality Saturation
Chenyun Yin, Youwei Xiao, Yuze Luo +2
Equality saturation (EqSat) is a powerful optimization paradigm that compactly represents many equivalent programs in an e-graph and delays commitment until extraction selects a lo…
Hive: A Multi-Agent Infrastructure for Algorithm- and Task-Level Scaling
Zizhang Luo, Yuhao Luo, Youwei Xiao +3
Large language models are increasingly deployed as complex agentic systems that scale with task complexity. While prior work has extensively explored model- and system-level scalin…
SkyEgg: Joint Implementation Selection and Scheduling for Hardware Synthesis using E-graphs
Youwei Xiao, Yuyang Zou, Yun Liang
Hardware synthesis from high-level descriptions remains fundamentally limited by the sequential optimization of interdependent design decisions. Current methodologies, including st…
Cement2: Temporal Hardware Transactions for High-Level and Efficient FPGA Programming
Youwei Xiao, Zizhang Luo, Weijie Peng +2
Hardware design faces a fundamental challenge: raising abstraction to improve productivity while maintaining control over low-level details like cycle accuracy. Traditional RTL des…
Aquas: Enhancing Domain Specialization through Holistic Hardware-Software Co-Optimization based on MLIR
Yuyang Zou, Youwei Xiao, Chenyun Yin +6
Application-Specific Instruction-Set Processors (ASIPs) built on the RISC-V architecture offer specialization opportunities for various applications. Existing frameworks are largel…
