I. INTRODUCTION Signal processing and telecommunication applications require FFT implementations that can perform large size, low latency computations while exhibiting low power consumption [12]. These demanding computational tasks are executed either by a single, high frequency embedded processor [5] or by using an Application Specific Integrated Circuit(More)
The stochastic Greenberg-Hastings cellular automaton is a model that mimics the propagation of reaction-diffusion waves in active media. Notably, this model undergoes a phase transition when the probability of excitation of a cell varies. We developed a specific FPGA design to study the critical behavior of this model. Using dedicated architectural(More)
