摘要
以JBits2.8软件包和XSV300开发板为平台,进行了Led控制器电路的外部和内部演化实验,目的是在FPGA中演化出8个Led灯的控制电路,使其实现根据时钟脉冲从1到8号按顺序依次闪亮的功能。通过统计数据分析了Hereboy算法中变异率和搜索率的取值。实验结果表明,对于小规模数字电路演化而言,FPGA较低的配置速度使外部演化的表现优于内部演化。
A led controller circuit was evolved successfully, by both means of ＂on-line＂and ＂off-line＂ evolution, using JBits2.8 API and XSV300 board. Eight leds on the board could flash orderly from No.1 to No.8 under the impulse of clock signal, The choosen of mutation rate and search probability in Hereboy algorithm was analyzed according to statistic data . Experiment result indicated, as far as small digitial circuit concerned, low speed of FPGA configuration made the performance of off-line evolution behaved better than on-line one.
