DCO: Dynamic Cache Orchestration for LLM Accelerators through Predictive Management

Read the original on arXiv AI →

The paper proposes DCO, a dynamic cache orchestration scheme for multi-core AI accelerators that uses application-aware policies and dataflow information to guide cache replacement, bypass decisions, and thrashing mitigation. Using a cycle-accurate simulator, the authors demonstrate up to 1.80× speedup over conventional cache architectures and validate the approach with an analytical model and RTL implementation. The design occupies 0.064 mm² on a 15 nm process and operates at 2 GHz, showing that a shared system-level cache can simplify programming while boosting performance for large language model workloads.

CACHEFORGE: LLM-Guided End-to-End Generative Cache Replacement Policy for Performance and Hardware Efficiency

CACHEFORGE introduces a novel framework that uses a large language model (LLM) to evolve cache‑replacement policies end‑to‑end. In each iteration, the LLM generates new C++ replacement logic, which is evaluated by a trace‑based simulator and refined through reward shaping, structural checks, and mutation. The resulting policies are compact, hardware‑aware, and outperform existing CRC‑2 baselines on SPEC CPU2006, achieving significant improvements in hit rate and IPC across diverse workloads.
