Abstract
A high-energy-efficiency binary neural network accelerator applicable to artificial intelligence Internet of Things is provided. 0.3-0.6V sub/near threshold 10T1C multiplication bit units with series capacitors are configured for charge domain binary convolution. An anti-process deviation differential voltage amplification array between bit lines and DACs is configured for robust pre-amplification in 0.3V batch standardized operations. A lazy bit line reset scheme further reduces energy, and inference accuracy losses can be ignored. Therefore, a binary neural network accelerator chip based on in-memory computation achieves peak energy efficiency of 18.5 POPS/W and 6.06 POPS/W, which are respectively improved by 21× and 135× compared with previous macro and system work [9, 11].
