基于PowerQUICC处理器的高速以太网接口设计

PowerQUICC处理器专门针对融合、兼容和成本问题而设计。PowerQUICC处理器基于e500 Power Architecture技术的SoC平台开发,采用QUICC Engine技术和集成安全引擎。重点介绍了一种基于PowerQUICC处理器的高性能通信处理器模块及在此基础上实现的2种高速以太网接口,包括用eTSEC实现的高速以太网接口和用QUICC机实现的高速以太网接口,最后通过测试得到了这2种接口的性能,并加以比较。

Design on High-speed Ethernet Interface Based Power on Processor QUICC

The PowerQUICC processor is specially designed to realize the integration, compatibility and cost reduction. This processor is developed with SoC platform based on e500 Power Architecture technology, and adopts the QUICC Engine technology and the integrated security engine. This paper mainly introduces a high-performance communication processing module based on PowerQUICC processors and two kinds of high-speed Ethernet interfaces based on the processing module, including the high-speed Ethernet interface based on eTSEC and the high-speed Ethernet interface based on QUICC engine. Finally, the performances of two interfaces are tested and compared.
