clFFT Contents
--------------
The clFFT library is an open source OpenCL library
implementation of discrete Fast Fourier Transforms. It:
* Provides a fast and accurate platform for calculating
discrete FFTs
* Supports 1D, 2D, and 3D transforms with a batch size
that can be greater than 1
* Supports complex and real transforms
* Supports planar (real and complex components in
separate arrays) and interleaved (real and complex
components as a pair contiguous in memory) formats
* Supports dimension lengths that can be any mix of
powers of 2, 3, 5 and 7
* Supports single and double precision floating-point
formats
* Supports in-place or out-of-place transforms
clFFT - Release Notes - version 2.8.0
--------------------------------------
New features of this release:
* Support for power-of-7 size transforms
* Pre-callback feature that enables custom pre-processing
of input data directly by the library with user callback function
* Support for 1D large size transforms with no extra memory allocation
requirement for certain sizes
Driver notes:
* This library version has been tested with Catalyst
Pro driver version 14.502 on Firepro W9100.
clFFT - Release Notes - version 2.6.1
--------------------------------------
This is a patch update release to v2.6.0. It has the following.
* Fix for client application crash with Linux 14.502 driver
* Performance fixes for real forward and backward transform when
enabling ECC
* Performance fixes for complex transforms over a small range in
power-of-2 sizes
* Improvement in API timing in client
* Several minor enhancements and bug fixes
Driver notes:
* This library version has been tested with Catalyst
Pro driver version 14.502 on Firepro W9100.
clFFT - Release Notes - version 2.6.0
--------------------------------------
New features of this release:
* Significant uplift of 1D real forward transform
performance for power-of-2 sizes
* Significant uplift of large 2D/3D real transform
performance for power-of-2 sizes
Known issues:
* Size limit on 1D real transforms remain at 2^24
for single precision and 2^22 for double
precision
Driver notes:
* This library version has been tested with Catalyst
Pro driver version 14.301 on Firepro W9100.
clFFT - Release Notes - version 2.4.0
--------------------------------------
New features of this release:
* Significant uplift of 1D complex transform performance
* 1D large size limit relaxation for complex transforms
* 2D/3D size limit relaxation on real and complex transforms
* Binary caching feature
* Several minor fixes and improvements
