TileFuse: A Fused Mixed-Precision Kernel Library for Efficient Quantized LLM Inference on AMD NPUs

TileFuse is a new kernel library that enables efficient quantized large language model inference on AMD's XDNA2 NPUs by supporting industry-standard quantization formats like AWQ directly, rather than requiring model reshaping. The technology delivers up to 2x improvements in latency and energy efficiency on edge devices, making practical LLM deployment on consumer hardware substantially more viable.

AscendKernelGen: A Systematic Study of LLM-Based Kernel Generation for Neural Processing Units

Researchers have developed AscendKernelGen, an LLM-based framework that dramatically improves code generation for neural processing units (NPUs) by combining domain-specific training data with reinforcement learning. The system achieves 95.5% compilation success on complex kernels, up from near-zero baseline performance, addressing a critical bottleneck in AI hardware optimization.

When Good Enough Is Optimal: Multiplication-Only Matrix Inversion Approximation for Quantized Gated DeltaNet

Researchers propose a fast matrix multiplication-based algorithm for matrix inversion in linear attention mechanisms, achieving up to 5x speedup on neural processing units while maintaining model accuracy under both standard and low-precision inference. The method addresses a critical computational bottleneck in long-context language modeling by using truncated Neumann expansion and parallel residual correction.

A-IO: Adaptive Inference Orchestration for Memory-Bound NPUs

A-IO addresses critical memory-bound bottlenecks in LLM deployment on NPU platforms like Ascend 910B by tackling the 'Model Scaling Paradox' and limitations of current speculative decoding techniques. The research reveals that static single-model deployment strategies and kernel synchronization overhead significantly constrain inference performance on heterogeneous accelerators.
