摘要
给出了一个基于MPC8347芯片的嵌入式千兆网络的实现方案,实现了在大规模信号处理情况下的1000Mb/s网络数据传输接口,给出了硬件连接框图和U_Boot源代码的改写方法。同时对MPC8347网络接口设计过程中的相关问题进行了讨论,如外部存储器扩展、通信接口设计等。并给出了相应的解决方案。
An embedded Gigabit network project based on MPC8347 is proposed, which realizes a 1000Mb/s network interface in massive signal processing. Hardware connecting means of plot of pane and software flow chart are given. Some related problems in developing the MPC8347 network interface are discussed, such as the design of communication interface, external bus expansion,initialization and interruption, etc. The ways to solve these problems are put forward too.
