| 摘 要： | 采用基于现场可编程门阵列(FPGA)模型的数字电路函数级在线自适应进化方法,提出了一种新的有效的进化策略:根据目标电路的功能组成将目标电路分解为多个子模块单元,然后对多个子模块单元分别进行进化设计,再利用子模块单元进行预期目标数字电路的在线进化,以降低每一级进化的染色体长度和提高收敛速度.以4×2乘法器电路为例,用这种方法成功实现了数字电路在线进化,结果表明,与逻辑门级进化方法相比,该方法改善了在线进化时存在染色体过长、收敛速度缓慢、测试评估困难的状况,收敛速度提高了5倍左右.

| Abstract: | The paper presents a new strategy for effective evolution of digital hardware by using the on-line adaptive evolution of digital circuits at function level based on the field programmable gate array (FPGA) model. The strategy firstly divides the target digital circuit into several separate sub-units according to its functions, then makes on-line evolutionary design of every sub-unit, and lastly, on-line evolution of the desired circuit was implemented based on the designed sub-units. Thus, the length of chr... |
