fwJPEG contains low level routines that can be used to create a JPEG encoder or decoder such as libjpeg. Check out the APL sample application here:
It provides an implementation of IJG optimized with APL.
The link is broken. Is that code still available somewhere else?
That sounds interesting. Have you considered releasing a standard tarball with the APL
optimized libjpeg usable as a shared library plugin for standard libjpeg?
No we hadn't considered that. I hope we can work that into our development - or find a volunteer to help = )
Thanks for the input!
It looks like everything related to APL and JPEG have been deleted. If someone has something workable, it would be great to share it!
In my opinion and experience, fwJPEG is designed for AMD processors, even then libjpeg gives you a better result in terms of performance and accuracy in all processors irespective of the codepath and processor.
In a project, I've compared IPP versus libjepg, and I've got a 50% increase of performance on an ARM processor.
Maybe you are right for fwJPEG, but there is no sample to test before coding deeper with the library.
Update: We were using an older version of libjpeg. Version 7 seems to be as fast as IPP.
