A GPU Based Simulation Platform for Adaptive Frequency Hopf Oscillators

In this paper we demonstrate a dynamical system simulator that runs on a single GPU. The model (running on an NVIDIA GT325M with 1GB of memory) is up to 50 times fasterthan a CPU version when more than 10 million adaptive Hopf oscillators have been simulated. The simulation shows that theoscillators tune to the correct frequencies for both discrete and continuous spectra. Due to its dynamic nature the system is also capable to track non-stationary spectra. With the help of this modelthe frequency spectrum of an ECG signal (as a non-stationary signal) obtained and was showed that frequency domainrepresentation of signal (i.e. FFT) is the same as one MATLAB generates
