A Review on Implementation of Random Number Generation based on FPGA

Vishakha V. Bonde, A. D. Kale

Abstract: Random number generator is required extensively by many applications like cryptography, simulation, numerical analysis, text-to-speech etc. Most C libraries have a pair of library routines for initializing, and then generating random numbers. For parametric speech synthesis application, a random number generator is required to produce noise samples. Therefore, a need has been felt for the design of a dedicated hardware for random number generator that generates one random number per cycle so that text-to speech conversion is done in real time. A random number generator (RNG) is a device designed to generate a sequence of numbers or symbols that dont have any pattern. Hardware-based systems for random number generation are widely used, but often fall short of this goal, albeit may meet some of the statistical tests for randomness for ensuring that do not have any de-codable patterns.
