Hi,

I read sprugs4a.pdf "

KeyStone Architecture
Literature Number: SPRUGS4A
July 2012
Packet Accelerator (PA) User Guide

I cannot find the explanation of FDQ and DSTQ on page 20. Could you tell me what they are and/or where I can find that?

Thanks

    I would like to add one more question on previous post. On the same manual sprugs4a.pdf, page 16, 17, it says about configuration packet. I do not find a definition or example of configuration packet. Could you tell me that? thanks,

    Robert,

    There are a lot of documents that you will need to read to get all the information for some of these inter-related modules. Please start with the Multicore Navigator User Guide. It defines these terms better than just giving you what the letters stand for.

    FDQ = free descriptor queue
    DSTQ = destination queue

    Configuration of the PA is discussed in section 2.3 on page 2-2 (14/41). Some of the configuration APIs from the PA LLD (Low Level Drivers) will generate configuration packets which are interpreted differently by the PA than data packets. The LLD API abstract some of these hardware details for you.
