GRAU: Generic Reconfigurable Activation Unit Design for Neural Network Hardware Accelerators
arXiv:2602.22352v2 Announce Type: replace-cross Abstract: With the continuous growth of neural network scales, low-precision quantization is widely used in edge accelerators. Classic multi-threshold activation hardware requires 2^n thresholds for $n$-bit outputs, causing a rapid increase in hardware cost as precision increases. We propose a reconfigurable activation hardware, GRAU, based on piecewise linear fitting, where the segment slopes are approximated by powers of two. Our design requires only basic comparators and 1-bit right shifters, supporting mixed-precision quantization and nonline
The continuous growth of neural networks necessitates more efficient hardware, particularly for edge applications where low-precision quantization is crucial.
This development offers a potential breakthrough in designing more affordable and power-efficient AI accelerators, making advanced AI capabilities more accessible and reducing the energy footprint of AI.
The design of neural network activation units can become significantly simpler and more efficient, reducing hardware costs and increasing precision capabilities for edge AI.
