摘　　要：集成毛细管电泳(ICE)芯片信号采集与处理系统的微型化、智能化是ICE芯片能否得到广泛应用的关键。针对传统的ICE芯片扫描分析系统结构复杂、处理速度慢、体积大等弱点,设计了一种基于DSP+双口RAM+ARM的嵌入式ICE芯片扫描分析系统。该系统将高速DSP与在通讯、网络和实时控制方面具有独特优势的ARM处理器,以及实时性好、接口电路简单、数据传输量大的双口RAM结合起来,为开发高性能、集成化、便携式的新型微小生化分离分析系统奠定了一定的技术基础。Miniaturization and intelligentization of the signal sampling and processing system for capillary electrophoresis chips have become the key to decide whether ICE chips can be extensively used. Aiming at disadvantages such as complex architecture, inefficient perfor- mance and large in size of the traditional system, an embedded ICE chip scanning and analyzing system is designed, which integrates the high performance digital signal processor, the embedded ARM processor with particular advantages in network and real-time control, and dual - port RAM with excellent real - time performance, simple interface circuit and high capacity of data transmission. This investigation might establish certain technical foundation for the new integrated and portable biochemical separation and analysis micro - system with high performance.
