There have been introduced a number of systems with evolvable hardware on a single chip. To overcome the lack of flexibility in these systems, we propose a single-chip evolutionary system with the evolutionary algorithm implemented in software on a built-in processor. This architecture is implemented in a Xilinx Virtex-II Pro FPGA with an embedded PowerPC processor. This allows for a rapid processing of the time consuming parts in hardware and leaving other parts to more easily modifiable software. This platform will be beneficial for future work regarding both cost and compactness. Experiments have been performed on the physical device with software running in parallel with fitness computation in digital logic. The results show that the system uses only twice as much time when compared to a PC running at 10 times faster clock speed.
