Abstract
Technologies for generating an M-bit selection vector for a selector circuit that receives as input M binary values from a set of entropy-generation elements and outputs N binary values responsive to the M-bit selection vector are described. N bits in the M-bit selection vector are set to a first logic state, and M-N bits of the M-bit selection vector are set to a second logic state. A determination of which N bits in the M-bit selection vector are set to the first logic state is determined by a process. The process includes determining an accumulated Hamming weight value for M bit positions of the M-bit selection vector using K samples and identifying N bit positions in the M-bit selection vector using the accumulated Hamming weight values. The process sets the N bits corresponding to the N bit positions in the M-bit selection vector to the first logic state.
