Considering both the execution speed and design flexibility, we use a NIOS II processor to calculate weight for each particle and a hardware accelerator to update particles. As a result, execution efficiency of the proposed hardware/software co-design method of particle filter is significantly improved while maintaining design flexibility for various potential applications. To demonstrate the performance of the proposed approach, a real-time object tracking system under the proposed framework is established and presented in this paper. Experimental results have demonstrated that satisfactory results in real-time tracking of objects in video sequences can be obtained by using the proposed method.
