Abstract
The present invention relates to a system and method which has automatic enabling and disabling capabilities for prefetching and transferring sequentially located data from system memory to a First In First Out (FIFO) queue. When a Peripheral Component Interconnect (PCI) initiator signals for a data read, a minimum unit of data will be transferred from system memory to the FIFO queue. Only after seeing a certain number of consecutive data read requests from the same PCI initiator will the system begin to sequentially prefetch data from system memory and to transfer the prefetched data to the FIFO queue.
