This paper presents power aware hardware implementation of multiclass Support Vector Machine on FPGA using systolic array architecture. It uses Partial reconfiguration schemes of XILINX for power optimal implementation of the design. Systolic array architecture provides efficient memory management, reduced complexity, and efficient data transfer mechanisms. Multiclass support vector machine is used as classifier for facial expression recognition system, which identifies one of six basic facial expressions such as smile, surprise, sad, anger, disgust, and fear. The extracted parameters from training phase of the SVM are used to implement testing phase of the SVM on the hardware. In the architecture, vector multiplication operation and classification of pair wise classifiers is designed. A data set of Cohn Kanade database in six different classes is used for training and testing of proposed SVM. This architecture is then partially reconfigured using difference based approach with the help of XILINX EDA tools. For feature classification power reduction is achieved using reconfiguration.
