This paper presents an improved cluster-based Mesh architecture called Mesh of Tree. The intra-cluster interconnect has an optimized Tree topology allowing to connect external signals and local feedbacks to logic blocks inputs. Unlike the well known VPR cluster-based Mesh architecture, the depopulated local interconnect allows to consider sizeable clusters. Moreover density is improved and interconnect switches requirement is reduced by 42% compared to the VPR-based architecture.
