Based on modular design architecture, a particle updating accelerator module via hardware implementation for updating particles and a weight evaluation module implemented on a soft-cored processor for calculating weighting for each particle are respectively designed and work closely together to accelerate the execution process. Thanks to a flexible design, the proposed approach can tackle various problems of embedded applications without the need for hardware redesign. Experiment results have demonstrated that the proposed HW/SW co-deign approach to realize particle filters has good computational efficiency to achieve a high-quality solution effectively. Finally, we realize the proposed particle filter with multi-master system architecture design to establish an image processing system for real-time object tracking
