摘要
为了对障碍物距离精确测量,基于最新Zedboard FPGA(现场可编程逻辑阵列)开发板,采用软硬件协同的设计方法,设计了障碍物距离测量系统的软硬件。系统为智能小车平台提供了完整的距离测量服务,测距范围能够达到2 cm^4.5 m,精度可达0.2 cm。该设计包含从底层硬件电路设计、可编程逻辑IP(Intellectual Property)核设计、到Linux设备驱动的设计全部流程,对于在Zynq-7000 FPGA上软硬件从事开发的人员有一定的参考价值。
Based on development board known as the latest Zedboard FPGA（field programmable logic array）,an obstacle distance measurement system was designed with the collaborative design method of hardware and software to provide a precise measurement of obstacle distance. A complete distance measurement service is provided by the distance measurement system for intelligent cars. The range of system′s rangefinding is 2~450 cm,and its precision can reach 0.2 cm. The whole design flow con-sists of underlying hardware circuit design,programmable logic IP （intellectual property） core design and Linux device driver design. It is useful to the hardware and software developers working with the Zynq-7000 FPGA.
