摘要
LwIP是瑞典计算机科学院开发的一个开源TCP/IP协议栈。主要论述了在ADSP-BF538上移植实时操作系统μC/OS-Ⅱ及LwIP协议栈,使其可以和上位机进行以太网通信,进而上位机就可以通过以太网下载程序到ADSP。并把这种下载方式应用到多DSP并行计算系统中,和过去的下载方式相比,这种下载方式简化了下载步骤,提高了下载效率。
LwIP is a TCP/IP protocol stack of open source and is developed by Sweden academy of computer sciences.This paper mainly discusses how to transplant the real-time operating system μC/OS-Ⅱ and LwIP protocol stack to the ADSP-BF538,make it have a Ethernet communication with PC,and PC can download program to ADSP through the Ethernet.This download way can be used in multiple DSP parallel computing system.Contrasting to past way,this way simplifies the download step and improves the efficiency of the download.
