Abstract:
A data conversion method for converting first n-bit data into second data including one or more m-bit data, where n and m (n>m) are natural numbers, comprising the steps of:(1) dividing the first data into a first bit group of k most significant bits, a second bit group of the next m bits, and a third bit group of the remaining h bits, respectively; (2) outputting a first predetermined m-bit value as many times as the value of the first bit group when the value of the first bit group is not equal to 0; (3) comparing the value of the second bit group with the first predetermined m-bit value, and outputting a second predetermined m-bit value that is different from the first predetermined m-bit value if the value of the second bit group is equal to the first predetermined m-bit value, or outputting the value of the second bit group if the value of the second bit group is different from the first predetermined m-bit value; and (4) configuring the second data by combining the one or more outputted m-bit values.
