Logic for detecting zero hot, one hot, and multi-hot vectors

Abstract

A method of detecting vector values includes receiving an input vector of bits. The input vector has a vector length. The method also includes generating a reverse input vector as a reverse of the input vector. The method further includes encoding the input vector as a function of a number of bits for indexing the input vector to generate an encoded input vector. The method still further includes encoding the reverse input vector as the function of a number of bits for indexing the reverse input vector to generate an encoded reverse input vector. The method also includes setting one hot to TRUE in response to the encoded input vector being equal to an inversion of the encoded reverse input vector.
