CONFERM: Recurrence-Aware Temporal Mapping for Multi-Cycle Multi-Context CGRAs

Throughput in DSP and machine learning workloads is often limited by two temporal structures, i.e., loop-carried recurrences and long-latency, multi-cycle compute nodes. On spatio-temporal coarse-grained reconfigurable arrays (CGRAs), both bottlenecks can be addressed by overlapping iterations across the multi-context...

HiKV: Hierarchical Importance-Aware KV Cache with Hardware Acceleration for LLM Decoding

HiKV is a novel algorithm-hardware co-design that exploits KV cache redundancy through hierarchical importance awareness and outperforms state-of-the-art importance-based methods by achieving an additional 1.87x reduction in external memory accesses.

ARES: Adaptive Reasoning-Effort Steering for PPA- and Cost-Aware RTL Optimization with LLM Agents

A normalized dollar cost per LLM call reported alongside the figure of merit (FoM) is introduced, enabling fair comparison across effort levels and optimizers and finding the construction of the long-term memory matters little.
