设计了基于FPGA和USB接口技术的新型电视跟踪性能测试仪。在介绍硬件设计方案的基础上,描述了生成模拟目标和判断跟踪状态的FPGA内部软件结构。选择LabWindows/CVI语言搭建测试仪的软件平台,并采用调用动态链接库的方法,完成了上位机和测试仪的USB通信软件设计。
Design a new television tracking performance tester based on FPGA and USB interface technology. Based on the introduction of the hardware design scheme, the software structure of FPGA inside the simulation target and the tracking status is described. Select LabWindows / CVI language to build a tester software platform, and use the method of calling the dynamic link library to complete the host computer and the tester USB communication software design.
