Abstract
Apparatus for detecting the leftmost '1' bit or the rightmost '1' bit of an input number includes a binary tree (11) of two-inputs OR-gates (13, 14, 15, 16) or their logical equivalent to which the input number is applied in parallel and from which signals are derived and applied as inputs and to control a plurality of trees (MA, MB, MC) of two-input multiplexers (12) from the outputs (E0, E1, E2, E3) of which appear the bits of a number representing the position in the input number of the leftmost '1' or the rightmost '1' bit.
