  • Means for reducing direct memory access
    Patent number: 6449665
    Abstract: In a method of reducing direct memory access in a machine employing a data segmenting scheme, transfer of a repetitive block of data is detected. The repetitive block of data repeats a data word of a predetermined value. A first invalid address is assigned to a current address pointer. The first invalid address indicates that the repetitive block of data is to be generated. A second invalid address is assigned to an end segment pointer. The second invalid address corresponds to the first invalid address plus a value indicating a number of repetitive data words that is included in the block of repetitive data. While the current address pointer has a value assigned thereto that is not equal to the second invalid address, a data word of the predetermined value is generated and the value assigned to the current address pointer is stepped.
