Fault-tolerant Image Filter Design using Particle Swarm Optimization

This paper describes mixed constrained image filter design with fault tolerant using Particle Swarm Optimization (PSO) on a reconfigurable processing array. There may be some faulty Configurable Logic Blocks (CLBs) in a reconfigurable processing array. The proposed method with PSO autonomously synthesizes a filter fitted to the reconfigurable device with some faults, to optimize the complexity and power of a circuit, and signal delay in both CLBs and wires. An image filter for noise reduction is experimentally synthesized to verify the validity of our method. By evolution, the quality of the optimized image filter on a reconfigurable device with a few faults is almost same as that with no fault.
