| Summary: | Chaotic systems are highly sensitive to initial conditions, where even minute changes can result in vastly different outcomes. The non-linear nature of chaotic systems prevents them from reaching a stable state, instead exhibiting continuous change. This inherent unpredictability makes chaotic systems particularly valuable in fields such as cryptography, random number generation, and secure communications, where the need for complex and difficult-to-predict patterns is crucial. FPGA chips allow for hardware-level customization, enabling the optimization of chaotic systems for specific tasks. Implementing chaotic oscillators and systems on FPGA platforms facilitates efficient solutions for security-related applications, including encryption, pseudorandom number generation, and secure communication protocols. Additionally, the high-speed performance, low power consumption, and parallel processing capabilities of FPGAs make them ideal for implementing chaotic systems in industrial and commercial applications, where efficiency and security are paramount. One of the most basic structures used in real time chaos-based applications is chaotic oscillators. In this study, FPGA based chaotic oscillators presented in the literature have been examined according to important parameters such as maximum operating frequency of the designed system, chaotic oscillator type, application area and numerical methods used for designs and the results have been discussed.
