This paper presents an on-line reconfigurable four-ary tree-based network on chip for distributed particle filters. The proposed architecture model provides the capability of fast prototyping a large scale of particle filters system basing on the idea of reusability. Furthermore, it supports dynamic reconfiguration by regrouping PEs so as to reduce the overall traffic loads on communication infrastructure. After formulating the regrouping into number partitioning problem, we apply two heuristic
