An Energy-efficient Floating-Point DNN Processor using Heterogeneous Computing Architecture with Exponent-Computing-in-Memory

Abstract of Proposed FP CIM Processor (1) Heterogeneous FP Computing Arch. : Separate optimization of FP computing: Realize 2 cycles FP MAC w/ CIM (2) Exponent Computing-in-Memory: In-memory AND/NOR + BL charge reusing: Total memory power 46.4% 2) Mantissa Free Exponent Calculation: Removing redundant normalization: Total MAC power 14.4%
