Abstract
Abstract An easy improvement of the Gold bit-reversal permutation algorithm is based on some observations concerning the distribution of pairs (i, revn (i)) in a set Z n = {0, 1, …, 2 n − 1} , where i ∈ Z n and rev n (i) is a bit-reversal of i. A number of consecutively inspected indexes is reduced to 2 n 4 . The improved algorithm preserves simplicity of the original and it saves 8% of the execution time on a PC/XT.
