A Flexible Bit-Stream Level Evolvable Hardware Platform Based on FPGA

A flexible bit-stream level evolvable hardware (EHW) platform is proposed in order to efficiently utilize the programmable logic resources of FPGA when evolving digital circuits. This platform is based on the FuDan FPGA device. An adaptive variable-size look-up-table (LUT) array structure is proposed with the optimal Genetic Algorithm to evolvable circuits. The experiment results showed that the proposed platform is more flexible, and it not only can make good use of FPGA logic resources, but also has a quick evolving speed.
