Abstract

A system and method of increasing the efficiency of a data processing system by alternately streaming portions of a large block of data from a large memory area into two memory banks within a smaller memory area using consecutive DMA transactions. Each streaming DMA transaction is entered in a DMA transaction queue and once it becomes active, transfers a block of data, the same size as one of the two memory banks, into one of the memory banks, after which it becomes inactive and is re-entered in the queue. When the streaming DMA transaction becomes active again, it switches to a different memory bank address and continues in the large data block where it stopped last time it was active. The streaming DMA transaction continues to be circulated in the queue until a total number of transaction iterations is reached, at which point the streaming DMA transaction is complete and is removed from the queue.
