Abstract: In consumer electronics, Holographic Counterpart Integration (HCI) is used to capture holographic images. The features from these images can be extracted using binary template matching techniques. Compute-In-Memory (CIM) technology as a crucial hardware acceleration technique, can significantly enhance the energy efficiency of the above operations. A hybrid 8T SRAM CIM architecture based on Matrix-Matrix Dot Product and Summation (MM-DPS) operations is proposed in this paper. The architecture decouples ADC usage from array capacity, effectively avoiding the increase in power consumption as the array width grows. Additionally, a CIM array design with multi-level bitlines and two-stage accumulation is introduced, along with a low-power RC-BSC ADC. The RC-BSC ADC ensures robustness against PVT variations and significantly reduces ADC usage. Implemented using 55nm CMOS technology, the proposed CIM macro achieves a throughput of 7489 GOPS and an energy efficiency of 17769.46 TOPS/W.
