AXi数据宽度转换器的Tuser和Tlast无法正常锁定

嗨，
我从摄像机接收视频信号。
它在一个时钟内发送十个像素的灰度等级。
因此它发送80位。我将它通过vid传递给axi，因此m_axi_vid_tdata是80位。
由于我想在此之后使用axi流ips，我使用axi数据宽度转换器向下转换为64位。
现在我看到的问题是，在我进行下变换之后，从数据宽度转换器出来的tlast和tuser的频率与来自摄像机的tlast和tuser的频率相同。
这很奇怪，因为自下变频以来，它应该以较低的频率发生。
现在终于我想再次发送它sxi到视频输出ip，如果我的tuser和tlast不真实对应SOF和EOL，我觉得数据不会被正确发送，并且axi到视频输出可能无法正常锁定。
有人请帮助我。
问候
斯里里

Hi,

I am getting in video signals from a camera. Which sends ten pixels of grey scale imgage in one clock. Thus it sends 80  bits.I pass it through vid in to axi and thus m_axi_vid_tdata is 80 bits. Since i want to use axi stream   ips after this , i use the axi data width converter to down convert to 64 bits.

Now the issue i see is, after i downconvert, the tlast and tuser coming out of the data width converter occur at the same frequency as the tlast and tuser coming from the camera . This is strange , as since i downconvert , it should occur at a lesser frequency.

Now finally i want to again  send it sxi to video out ip and if my tuser and tlast dont actuallty  corespond to SOF and EOL , i feel that the data wont be sent proeprly, and axi to video out may not lock properly.

Some one please help me on this.
