Can USDPAA be used to re-assemble a data stream?

Hi,

 

We are currently planning an application where we receive streaming data as UDP jumbo packets at a very high rate.

The UDP-payload contains a protocol specific header as well as the "real" payload, therefore a packet looks like: MAC:IP:UDP:CUSTOM_PROTOCOLL:payload

 

What we would like to achieve is to copy the payload without any headers into a continous ring-buffer, without manual CPU intervention (like memcpy).

Are the accelerators in the QorIQ series (LS2080A) capable of performing operations like the mentioned one?

 

Thank you in advance, Clemens
