摘要
探讨了一种运用SoPC技术,将Nios系统、DDS信号产生电路、等精度频率计电路嵌入到一块FPGA里,实现信号源的方案。由于FPGA可重配置的特性,信号源可以根据需要随时对主要功能进行修改,不必更换硬件。该信号源功能多,使用范围宽,精度高。系统的主要功能都在一块芯片上,抗干扰能力强,功耗低,体积小。
According to technology of SoPC , Nios system, DDS signal produces circuit and equal precision cymometer are embedded to FPGA together, realizes signal source plan. As FPGA can reeonfigure characteristic, signal source can be required at any time to amend main functions by need. The signal source is more functional, widely use, high precision. The systemic main functions all integrate on a chip, it has the strong antijamming ability, low power loss, small volume.
