UDP Protocol Manager by intoPIX

The IPX-UDP receives UDP packets (including video/audio assets) on a Gigabit Ethernet link. The MAC controller is based on the Tri-Mode MAC controller that is hard-coded from Xilinx technology. intoPIX configures the MAC controller with a specific MAC address read from a dedicated register and also sets up the external PHY chip. 

The protocol handler will manage the user UDP protocol. This handler is in charge of:

• 接收视频/音频数据包
• verifying the integrity with IP and UDP checksum and Ethernet CRC
• 每收到 n 个数据包发送响应数据包。

如果数据包丢失或损坏，UDP 处理程序将拒绝所有后续数据包，同时等待其相关 n 数据包组的正确重新传输。
