摘　　要：随着网络带宽的迅速增加,当网络带宽达到吉比特时,如果TCP/IP协议的处理还在主CPU 中进行,由于CPU是通用芯片,处理协议的效率不高,这样不但占用了大量的CPU资源,而且不能充分的利用带宽资源。本文用ASIC实现了TCP数据流的重组和交付,其速度可达到3.2GB。With the bandwidth of network increasing, if the TCP/IP protocol is processed in host CPU, not only take up plenty of resource of CPU, but also can' t make full use of the bandwidth of network, because the CPU isn' t dedicated chip, therefore the efficient of processing of protocol is low. In this paper introduce a ways to accomplish the reassembly and consignation in ASIC, which speed can achieves to 3 2GB
