【摘要】 在分析FTT1010-M型面阵CCD图像传感器驱动时序关系的基础上,设计了可调曝光时间的面阵CCD驱动时序发生器及其硬件电路.选用CPLD器件作为硬件设计平台,使用VHDL语言对驱动时序发生器进行了硬件描述.采用QuartusⅡ对所设计的驱动时序发生器进行了功能仿真,并针对ALTERA公司的EPM7160SLC84-10进行了RTL级仿真及配置.硬件实验结果表明,所设计的驱动时序发生器不仅可以满足面阵CCD图像传感器的驱动要求,而且还能够调节其曝光时间.更多还原

【Abstract】 Driving schedules of FTT1010-M frame transfer CCD have been examined in detail. The driving schedule generator with exposure time had hardware have been designed for array CCD camera. Complex programmable logic device (CPLD) is chosen as hardware design platform,and driving schedule generator has been described with VHDL. The function simulation of the system is successfully fulfilled and the design is fitted into EPM7160SLC84-10 (a CPLD produced by ALTERA). Hardware experiments show that designed generator is suitable for the driving of high-speed CCD image sensor,and the exposure time of camera could be adjusted according to different applications.更多还原
