VHDL implementation for a pseudo random number generator based on tent map

Pseudo random numbers are used for several proposes where uniformity data is desired. For generating them, there are some useful methods, feedback shift registers and dynamical functions are most common methods. Among dynamical functions, onedimensional chaotic maps are the simplest ones. The tent map is a piecewise-linear onedimensional map that has been used to generate pseudo random numbers. Its mathematical description originally was delimited from zero to one, so an adjustment was needed for fixing to digital implementation. After adjusting has been made, some dynamical testes were applied to verify if adjusting did not affect its functioning. The next step was to implement the map using VHDL; such implementation was simulated and ratified using a Matlab script. Summarizing, it was achieved a method for easy generation of pseudo random numbers.
