<p>A method for changing the bit-order of a data value in a data processing system having a register capable of storing data strings which each comprise a plurality of sub-strings that are not individually addressable, the method comprising assigning an output data string by the steps of: loading the data value into a first data string; generating, for each sub-string of the output data string, a corresponding intermediate data string, each sub-string of which corresponds to a selected bit on the first data string and has all its bits equal to the value of the selected bit; and and generating the output data string, in each sub-string of which each bit has the same value as the bits in a selected sub-string of the intermediate data string that corresponds to that sub-string of the output data string. <IMAGE></p> |
