基于CPLD 和DSP 设计了线阵CCD 检测系统，CCD 的时序驱动由CPLD 实现，经过运放后的视频信号由TMS320F2812 进行采集和处理，此检测系统已成功应用于医药包装行业的数粒机系统，能够可靠地实现Φ2mm 以上各种形状的药粒计数，计数速度可达3000-8000 粒/分钟。关键词：CPLD，DSP，线阵CCD，数粒机Abstract：A linear CCD detecting system was designed based on CPLD and DSP, which was used in an advanced counting-machine. The time sequence of CCD-driving was implemented by CPLD, and the analog signal of video was deal with TMS320F2812, the system has applied in the medicine packing counting-machine and can count capsules above Φ2mm. The counting speed can reach 3000-8000 capsule per minute.Key word: CPLD，DSP，Linear CCD，Counting-Machin
