hcFFT has been deprecated and has been replaced by rocFFT

A. Introduction:

This repository hosts the HCC based FFT Library, that targets GPU acceleration of FFT routines on AMD devices. To know what HCC compiler features, refer here.

The following are the sub-routines that are implemented

1. R2C : Transforms Real valued input in Time domain to Complex valued output in Frequency domain.
2. C2R : Transforms Complex valued input in Frequency domain to Real valued output in Real domain.
3. C2C : Transforms Complex valued input in Frequency domain to Complex valued output in Real domain or vice versa

To know more, go through the Documentation
