Look at the picture, given the producer is GPIF in master mode, the consumer is endpoints for USB, whatever the producer sockets or the consumer sockets, they are both in memory (Sysmem).
The dataflow maybe have 3 steps as below
So question is :
1, In step ②，what make the data flow from producer sockets to consumer sockets?
2,In step ①，to write the data into producer sockets(the secrete Sysmem) , the data pins and address pins are occupied; in step ② ，the data pins and address pins are occupied; and so is the step ③。So how can they run parallelly to keep a 100M*32bit throughput.
sorry the picture can't show , so I put it in the attachment
