An Ultra-Low Power Always-On Keyword Spotting Accelerator Using Quantized Convolutional Neural Network and Voltage-Domain Analog Switching Network-Based Approximate Computing

An Ultra-Low Power Always-On Keyword Spotting Accelerator Using Quantized Convolutional Neural Network and Voltage-Domain Analog Switching Network-Based Approximate Computing

An ultra-low power always-on keyword spotting (KWS) accelerator is implemented in 22nm CMOS technology, which is based on an optimized convolutional neural network (CNN). To reduce the power consumption while maintaining the system recognition accuracy, we first perform a bit-width quantization meth...
