CacheFit: The Rising Cost of Cache Replacement and Constraint-Driven Redesign of Last-Level Cache Replacement Policies

The latency, power, and area costs of LLC replacement remain poorly explored not because simulators cannot be instrumented--event counters feeding a power model are routine--but because no cost model takes a replacement policy as input. CACTI and McPAT price regular structures, a cache or a core, not the small, oddly s...

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

CACHEFORGE is the first framework to evolve cache-replacement policies end-to-end by embedding a large language model inside a governed hardware-aware loop and enforces feasibility through reward shaping, structural checks, dynamic mutation, temperature scheduling, and cross-policy crossover.
