各位高手帮我看看，我的chain配置有什么问题
Chris Meng：
回复 user1178538:
你好，
IPC frameout应该是两个异核之间使用的，例如M3和DSP。两个M3之前用ipclink吧。你看看现有的采集显示的代码。
Chris Meng：
回复 Chris Meng:
采集和显示是在同一个M3里面的。
user1178538：
回复 Chris Meng:
谢谢你的回复，我是想将经过DSP处理的结果也要显示出来，之前我在IPC FRAME OUT之后接的是ｓｗｍｓ link–>display link，这样是正常的，但是经过ｓｗｍｓ link，图像会延时一到两帧，所以我不想用ｓｗｍｓ link，这样的话IPC FRAME OUT该如何接display link呢？

回复 Chris Meng:
对，是贴错了，就是上面代码没经过swms link就出错

ipcframeout的输出是420SP
