A Hardware-Error-Aware Time-Domain CIM Accelerator for AdderNet with Significance-Aware Dual-Mode DTC Encoding and Shared-Clock TDC Readout

Applied Sciences
Adder neural networks remove multiplication from convolution, yet their direct L1-distance datapath still requires subtraction, absolute-value generation, and wide accumulation. We address this cost by mapping the online L1 operation to minimum selection
