基于CPLD的空间CCD相机下位机系统的设计

Design for Lower-computer of Space CCD Camera Based on CPLD

结合空间面阵CCD相机电子系统的总体要求,完成了基于CPLD的空间面阵CCD相机下位机系统的设计.使用VHDL语言对下位机系统进行了硬件描述。针对ALTERA公司的CPLD器件EPM7160SLC84-10对设计进行了RTL级仿真及配置。实验结果表明,所研制的基于CPLD的下位机系统不仅可以满足与CCD相机上位机进行高可靠性串行通信的要求,还可以监测和控制相机的工作状态。

Design of lower computer system has been finished for the electronic system of space CCD cameras based on requests. The lower computer system is described with VHDL. The RTL simulation is fulfilled and design is fitted into EPM7160SLC84-10 （a kind of CPLD products that made e2v） ; Experiments show that the finished lower-computer system can fulfill the requests for communication with upper computers dependably; therefore the states of space CCD cameras can be inspected and controlled.
