Centar is a full service resource for development of embedded signal processing circuit designs requiring use of a discreet "Fourier transform” (DFT), typically implemented as a “Fast Fourier Transform” (FFT). Centar’s FFT technology is programmable, so that different FFT functionality, including non-power-of-two transform sizes, can be developed by simply re-programming the same circuit, significantly lowering the licensing cost of a design to customers. At the same time Centar uses an array-based implementation to provide high-performance, scalable throughputs and by design all circuit communications are "localized" leading to high clock speeds and low power implementations.
Floating-point (IEEE 754) IP based on Arria 10 and Stratix 10 FPGAs
This circuit uses Altera’s new Arria and Stratix 10 FPGAs with hardwired support for floating-point operations (IEEE754).
The transform computation is based on a new matrix formulation of the discreet Fourier transform1 (DFT) which decomposes it into …
