摘要：

An energy-efficient hardware architecture of a self-organizing map (SOM) for ECG clustering is proposed. It detects an R-peak, reconstructs the QRS complex around it, and clusters the complex by calculating the Euclidean distance between the complex and the weight vectors of each cell in the SOM network (i.e., 5x5 cells). In the operation mode, the cluster ID related to the minimum Euclidean distance is provided, while the tagged weight vectors are updated in the learning mode. The proposed SoC is 1735 x 1020 mu m(2) in CMOS 65-nm LP, and it consumes 5.853 mW at VDD = 1.2 V.
