Research of software component technology for network processor

Network processors usually consist of multiple heterogeneous processing and memory units connected by on-chip network, and they are used as central device and perform the tasks in data plane of network applications in critical network environment. Network processor based systems are complex embedded system, which are real-time, resource-constrained and heterogeneous, Component technology is a promising approach for efficient software development. However, the general purpose component technology is not suitable for the contexts of network processor. This paper focused on applying component technology to network processor based systems. The component technology discussed also could be used in other similar multicore systems.
