一种连续电子变倍算法的 SOPC 实现架构

摘要

A SOPC implementation architecture of continuous electronic zooming based on the bilinear interpolation was proposed.According to the characteristics of FPGA and NIOS,the stepless continuous electronic zooming was a-chieved in real -time by SOPC with one FPGA,which can reduce the designing difficulty and greatly reduce the occu-pation of hardware resources.The results show that this method has a good effect of electronic zooming and can im-prove the resolution capability of small target in the image,and has good application value in the imaging systems.%基于双线性插值算法提出一种连续电子变倍的 SOPC 实现架构。该方法充分利用 FP-GA 和 NIOS 软核各自优势，以单 FPGA 的 SOPC 实时实现了无级连续电子变倍功能，在减小设计难度的同时大大降低了对硬件资源的占用。实验结果表明，本文架构具备较好的电子变倍效果，可提高观察者对图像中小目标的分辨能力，在成像系统中具有较好的应用价值。
