摘　　要：网络处理器通常由多个异构的处理和内存单元通过片上网络连接构成,其目标应用需要在Gbit/s到几十Gbit/s的网络环境中以线速处理数据包,具有实时、资源受限和异构的特点,目前的系统设计和开发方法难以达到性能和效率兼顾。通过分析硬件和应用,总结在基于网络处理器的系统中应用组件技术的基本原则,可应用组件技术来解决传统方法的问题。提出的组件模式抽取了网络处理器在硬件体系结构和目标应用方面的特征,可以简化系统建立并能够对系统行为进行预测。Network processors usually consist of multiple heterogeneous processing and memory units connected by on-chip network, and the target applications generally need to process packets at full line rate from Gbit/s to multiple 10 Gbit/s. Network processor based applications are real-time, resource-constrained and heterogeneous. Component technology is a promising approach for complex embedded system development. However, the general purpose component technology is not suitable for the contexts of network processor. The hardware architecture and applications are analyzed and general guidelines are given to applying component technology to network processor based systems. A component model is proposed according to simplify system composition and improve predictability.
