1. In a video motion estimation processor, a method of generating a Sum of Absolute Differences (SAD) value for differences between a set of two numbers, the method comprising:

  • in a processor, creating a first total value equal to a total of all of the numbers in a first set of numbers;

    in the processor, creating a second total value equal to a total of all of the numbers in a second set of numbers;

    in the processor, combining the first total to the second total to get an intermediate total;

    in the processor, determining which of first and second values in the first set of numbers and the second set of numbers, respectively, is the smaller values;

    in the processor, doubling the smaller values;

    in the processor, summing the doubled smaller values; and

    generating a final result SAD value that equals the intermediate total less the doubled smaller value.
