ABSTRACT:
A high-throughput memory access interface allows higher data transfer rates between a system memory controller and video/graphics adapters than is possible using standard local bus architectures. The interface enables data to be written directly to a peripheral device at either one of two selectable speeds. The peripheral device may be a graphics adapter. A signal indicative of whether the adapter's write buffers are full is used to determine whether a write transaction to the adapter can proceed. If the transaction can not proceed at that time, it can be enqueued in the interface.
