【摘要】：利用位流重定位与差异配置技术对现有基于动态部分重构的演化硬件实现方法进行改进,以解决其演化复杂电路时位流存储开销大和演化速度慢的问题。利用Xilinx早期获取部分重构技术,定制能实现位流重定位的可演化IP核。原始位流文件经设计形成算子核位流库存于外部CF卡上,方便系统调用。将现场可编程门阵列片内软核处理器Micro Blaze作为演化控制器,采用染色体差异配置技术,在线实时调节可演化IP核的电路结构,构成基于片上可编程系统的自演化系统。以图像滤波器的在线演化设计为例,在Virtex-5现场可编程门阵列开发板ML507上对系统结构和演化机制进行验证,结果表明,所提演化机制能有效节省位流存储空间,提高演化速度。
[Abstract]:The existing evolutionary hardware implementation method based on dynamic partial reconfiguration is improved by using bitstream relocation and differential configuration techniques to solve the problems of high bit stream storage overhead and slow evolution speed in complex evolving circuits. Based on the early acquisition of partial reconfiguration in Xilinx, an evolutionary IP kernel is customized to realize bit stream relocation. The original bit stream file is designed to form the core bit stream of the operator stored on the external CF card, which is convenient for system call. Based on the on-chip programmable gate array (FPGA) soft core processor (Micro Blaze), a self-evolving system based on on-chip programmable system is constructed by using chromosomal differential collocation technique and on-line real-time adjusting the circuit structure of the evolving IP core. Taking the on-line evolution design of image filter as an example, the system structure and evolution mechanism are verified on Virtex-5 field programmable gate array development board ML507. The results show that the proposed evolution mechanism can save bit stream storage space effectively. Improve the speed of evolution.
