In the architecture, the updating of different synaptic weight vectors are divided into a number of stages. The results of precedent stages will be used for the computation of subsequent stages for expediting training speed and lowering the area cost. The proposed architecture has been embedded in a system-on-programmable-chip (SOPC) platform for physical performance measurement. Experimental results show that the proposed architecture is an effective alternative for fast PCA attaining both high performance and low computational time.
