also provide an efficient PRNG for GPU respecting based on IC. Such devices
allows us to generated almost 20 billions of random numbers per second.

+In order to establish that our PRNGs are chaotic according to the Devaney's
+formulation, we extend what we have proposed in~\cite{guyeux10}. Moreover, we define a new distance to measure the disorder in the chaos and we prove some interesting properties with this distance.
The rest of this paper is organised as follows. In Section~\ref{section:related

PRNGs is studied. Section~\ref{sec:efficient prng} presents an efficient
implementation of our chaotic PRNG on a CPU. Section~\ref{sec:efficient prng
