The AXI-4 Stream Accelerator is a relatively new IP block. I am looking to use this block to modify AXI-4 streaming data on the fly in order to encapsulate it in an Ethernet protocol. This would involve streaming the data on the slave side into block ram, adding the proper header and calculating the checksum, and then streaming it out the master side to a 10GE MAC. Has anyone used this block or is knowledgable enough about it to be able to tell me if this is a viable application? I went throught the data sheet but obviously I don't understand it enough at this point to really know.
