Resumen: Chaotic oscillators have been implemented using embedded systems like field-programmable gate arrays (FPGAs). Their applications in secure communications require the synchronization of them in a master-slave topology, for instance. However, this is not a trivial task because one must guarantee a low synchronization error that depends on the selection of an appropriate step-size of a numerical method. That way, this paper describes how to select the step-size for a successful simulation and how to implement the master-slave synchronization of two chaotic oscillators using FPGAs. We discuss details on the numerical simulation of the synchronization using the seminal work of Pecora & Carroll and also discuss FPGA issues. Finally, we implement a chaotic secure communication system to show that synchronization methods with high error produce loss of data, as shown by the transmission and reception of a color image using two chaotic oscillators.
