  • Patent number: 5890220
    Abstract: In a computer system having an address converter for DMA (direct memory access), an address conversion apparatus in which a memory area to be accessed by the DMA can be accessed at high speed from a CPU. A "DMA address conversion area" is defined in a memory space, and address conversion means in the mode of accessing the DMA address conversion area is so constructed that, when the area has been accessed from the CPU, a physical address is generated in accordance with the address conversion routine of the DMA address conversion means or converter, so as to access a main storage. The memory area to be accessed by the DMA can be quickly accessed from the CPU without requiring such an operation as especially accessing the control ware of the address converter or producing the physical address under the management of a program run on the CPU.
