摘　　要：提出了采用硬件状态控制位寄存器和进程挂起模块相结合的设计思路,该方案不但成功避免了网络处理器微码转发程序多进程间资源访问冲突的问题,而且有效减少了微码转发程序中的指令个数,使传统软件方式下普遍存在的微码转发效率低的弊病得到彻底解决,提高了网络处理器的工作效率。A new method which combine the register of state flag with process hang-up module in network processor is presented. It can not only avoid the collision among multi-process when they visit same resource, but also greatly decrease the totle number of instruc- tions in microcode transmission program. The low-efficiency problem of traditional software method can be solved thoroughly, and the work efficiency of the network processor is highly increased.
