The Bus Interface Unit is responsible for merging and buffering all of the transactions that originate from the various initiator blocks inside the DMA controller into the 4 separate VBUSM initiator interfaces. Arbitration between the blocks to a given VBUSM interface is round robin within a single priority level. A 2 word deep retiming buffer is provided on each sub interface of each provided VBUSM bus.
