标题: AXI4 Stream中position byte是什么意思?

如题,在Stream中分为2種数據,一種是postion byte,一种是data byte,data byte容易理解,就是要傳輸的数据。可是position byte是什么呢?里面包含的是什么內容?用于做什么的?如果能舉個小例子就更好了,请教高手解答,不勝感謝。

下面是摘自文档中的部分:
Data byte: A byte of data that contAIns valid information that is transmitted between the source and destination.
Position byte: A byte that indicates the relative positions of data bytes within the stream. This is a placeholder that does not contain any relevant data values that are transmitted between the source and destination.
