HC-FFT: highly configurable and efficient FFT implementation on FPGA
FFT is one of the basic building blocks in many applications such as sensors, radars, communications. For some applications, e.g., real-time spectral monitoring and analysis, FFT needs to be”run-time configurable” so that the system is real-time. When examining the previous work on configurable real-time (FPGA-based) FFT implementations, we see that ...

FFT-based Option Pricing [PDF]
The Black-Scholes formula, one of the major breakthroughs of modern finance, allows for an easy and fast computation of option prices. But some of its assumptions, like constant volatility or log-normal distribution of asset prices, do not find justification in the markets. More complex models, which take into account the empirical facts, often lead to
