On-Chip Evolution Using a Soft Processor Core Applied to Image Recognition
To increase the flexibility of single-chip evolvable hardware systems, we explore possibilities of systems with the evolutionary algorithm implemented in software on an onchip processor. This gives higher flexibility compared to implementing an evolutionary algorithm directly in hardware, since the parameters and behaviour of the algorithm can easily be changed, and complex operators are more feasible to implement. In this paper a Xilinx MicroBlaze soft core processor is used, and the system is implemented in a Xilinx FPGA. A suitable hardware architecture for image recognition has been proposed, and it is applied to a face recognition task. Data buses and higher level functions have been utilized in order to reduce the search space for the evolutionary algorithm. Experiments have been performed on the physical device, with software running in parallel with fitness computation in digital logic. Results show that the MicroBlaze system evolves at half the speed of a Pentium M system ...
