摘要
随着计算机技术的飞速发展,虚拟仪器也得到了快速的发展。与传统仪器相比较,虚拟仪器在灵活性、多样性等诸多方面都占有优势。随着技术的不断更新,其应用将会越来越广泛,同时对虚拟仪器的要求将进一步提高。将TMS320F2812-DSP丰富的片上资源、较高的数据处理能力与功能强大的图形化编程虚拟仪器开发平台LabVIEW相结合,并通过USB接口将数据传送到PC机中,由LabVIEW进行信号显示与处理,实现了虚拟频谱分析仪的功能。
Recent years, virtual instrument has developed rapidly as the development of the computer technology. Compared to traditional instrument, virtual instruments have the advantage of diversity, flexibility and so on. We expect that virtual instrument will be applied more and more, and the technology used in virtual instru- ment will be updated continually . The design realizes the basal functions of Virtual spectrum analyzer by combining the abundant on - chip resources and better data - processing ability of TMS320F2812 - DSP with LabVIEW, which is a graphical programming virtual software developing platform owning powerful function.
