ABSTRACT:
A DMA device which can quickly access main memory over a system bus without requiring an allocation of a contiguous block of memory on start-up. This is accomplished by providing a copy of the host microprocessor's page table to the DMA device for the portion of memory allocated to it. The DMA device preferably stores at least a portion of the page table internally, with any remainder of the page table being stored in main memory at an address stored in said DMA device.
