摘要
随着数字电视的发展,高清电视机顶盒的需求会越来越大,而数字电视和IPTV的融合要求电视机顶盒要有较好的网络性能。ST平台的OS20/OS21操作系统不具备TCP/IP网络协议栈,为此,本文给出了轻量级网络协议栈LwIP在STi7109平台上的移植方案。实验表明,经过优化,LwIP在STi7109上能够获得较好的性能。
With the development of dgital TV, there will be demands on high definition set top box. The merge of digital TV and IPTV requires that the set top box should have a good network performance. As OS20/OS21 operation system have no TCP/IP protocol stack; this paper introduces the transplantation and optimization of LwIP on STi7109 Platform. The experiment results show that LwIP can achieve good performance on STi7109 platform.
