Noesis Technologies releases its Ultra High Speed FFT/IFFT processor IP Core

February 26, 2024 -- Noesis Technologies has announced today the immediate availability of its ntFFT_UHS IP Core that implements a customized FFT/IFFT programmable fixed point (Decimation in Frequency - DIF) transform processor, supporting low latency, streaming, ultra-parallel complex samples per clock cycle in natural order. Input, internal and output 2’s complement fixed point precision are fully configurable before IP synthesis. Radix-2, Radix-4 or Mixed-Radix design may be selected with parallel butterflies deployment, depending on the implemented transform sizes. Each stage features its own permutation network buffer, implemented optionally as either Register File or BRAM primitives. Twiddle factors fixed-point precision is selected via parameterization and the values are pre-calculated and stored in small distributed LUTs next to the respective butterflies, using a scalable design methodology. The permutation of each buffer stage is necessarily custom-made, since it is dependent on the parallel samples per clock cycle configuration and the supported FFT transform sizes. An optional Circular Shift buffer can be instantiated for those applications that need to correct a detected Carrier Frequency Offset in the frequency domain (FFT), with range of circular shifts correction relevant to both the FFT transform size and the parallel samples per clock cycle. Additional Overlap-Save (OLS) method wrappers may be provided to support real time high bandwidth filtering applications.

The ntFFT_UHS IP core can be used in a variety of applications, including Communication Systems, Spectrum Analysis, OFDM modems, Image processing, Streaming Filtering applications, Defense Receivers and Signal Monitoring, Medical and Scientific Instruments.
