| Abstract: | 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. |
