摘　　要：为了解决演化硬件实现过程中演化粒度较大造成资源浪费以及演化耗时长的问题,提出对FPGA资源-配置位流关系进行建模,在线生成位流的设计方法,并给出资源位流信息建模方法与位流在线生成算法。通过演化2位乘法器验证设计方法的有效性。结果表明:所提出的方法具有更低的资源代价和更高的演化速度。In order to solve the problem of resource waste and long evolution time caused by large evolution granularity in the process of evolution hardware implementation, a method of modeling the relationship between FPGA resource and bitstream was proposed to generate bitstream online. The relationship modeling of resource-bitstream and the online generation algorithm of bitstream are given. The validity of the design method is verified by the evolution of a 2-bit multiplier. The results show that the proposed method has lower resource cost and higher evolution speed.
