FFT Core for Adaptive Cruise Control Using FPGAs

A new type of speed control called Adaptive Cruise Control (ACC) (Figure 1) is being used on some new model vehicles. These systems allow you to set a following distance—or time interval—between your ...

Non-Power-of-Two FFT Circuit Designs Do Not Have to be Difficult

At the same time there are important disadvantages to using the power-of-two (P2) FFT, in particular limits on the number of reachable transform sizes that make it difficult to match data set sizes ...

How to build ultra-fast floating-point FFTs in FPGAs

Engineers targeting DSP to FPGAs have traditionally used fixed-point arithmetic, mainly because of the high cost associated with implementing floating-point arithmetic. That cost comes in the form of ...

RF Engines aims 200Msample/s pipelined FFT core at FPGAs

Isle of Wight-based RF Engines has released a 200Msample/s pipelined fast Fouriertransform (FFT) core for FPGAs. “The design uses a high degree of parallelism. We have not found anyone elseproviding ...

Floating-point FFT with Minimal Hardware

There is a natural preference to use floating-point implementations in custom embedded applications because they offer a much higher dynamic range and as a byproduct bypass the design hassle of ...
