GyRot framework boosts LLM inference with novel low-bit quantization

Researchers have developed GyRot, a novel framework and hardware accelerator designed to improve the efficiency of low-bit quantization for Large Language Model (LLM) inference. GyRot addresses the common accuracy degradation and hardware overhead issues when combining rotation and group quantization by introducing Coarse Rotation, Fine Grouping (CoRFiG), and Harmonic-Aligned Permutation (HAP). This approach enhances quantizability and reduces the precision needed for scaling factors. The framework also includes an integer-based dequantization strategy for further hardware cost reduction. When implemented on an INT4 tensor processing element architecture, GyRot achieved state-of-the-art 4-bit accuracy for LLaMA-family models, offering up to 3.4x speedup and 3.6x energy efficiency compared to existing LLM accelerators.
