Abstract
Where the first bit position having a predetermined value; e.g., 1, as viewed from the most significant bit (MSB) or least significant bit (LSB) of the input data, 1 is subtracted from the input data to provide a subtraction result. This subtraction result and the input data are provided to the inputs of an exclusive OR gate is applied to a priority encoder capable of encoding the first bit position having a 1 as viewed from the MSB. The output represents the first bit position having a 1 as viewed from the LSB, thus requiring only a single priority encoder capable of detecting the first bit position having a 1 as viewed from the MSB.
