Application specific coarse-grained FPGA for processing element in real time parallel particle filters

This paper presents an application specific reconfigurable architecture based on coarse-grain FPGA for real-time parallel particle filters. The architecture consists of a set of heterogeneous arithmetic units and buffer banks, where their interconnections are reconfigurable at the hardware level. The proposed architecture separates fixed and reconfigurable units for high-throughput realization. We compare potential throughput of the design with that of commercial FPGAs and DSPs. The proposed architecture is implemented in 0.25 μm CMOS process.
