HiKV: Hierarchical Importance-Aware KV Cache with Hardware Acceleration for LLM Decoding
Chao Fang, Jun Yin, Man Shi, Marian Verhelst
With the rapid adoption of long-context large language models (LLMs), the continuously growing KV cache during decoding has become the critical memory bottleneck. To tackle this challenge, we propose HiKV, a novel algorithm-hardware co-design that exploits KV cache redundancy thr…
