Abstract:
An embedded network project based on TMS320DM642 is proposed, which realizes a 100Mb/s network interface in massive signal processing, including hardware connecting means of plot of pane and software flowchart. Some related problems in developing the DM642 network interface are discussed, such as hardware-software compatibility, initialization, interruption and synchronization, out of memory, etc. The ways to solve these problems are put forward too.
