Experiments show that the lookup capability of network processor can be effectively improved with only a small number of cache entries per processing element. ( 4 ) A register file and a novel memory hierarchy component, called Split Control Cache, are proposed for network processors. 实验表明,每个处理单元中只要维护少量的缓存表项,就可使网络处理器的查找能力获得有效的提升。(4)提出了一种网络处理器存储子系统中寄存器堆和cache机制的设计方法。
