Quexal MMX goes freeware

Back in 2000, Quexal changed the way programmers had to deal with MMX programming. A friendly user interface simplified building parallel versions of algorithms, an optimizing compiler made sure that the resulting code would run fast, and a visual debugger helped pinpoint programming errors.

Even if the focus of the programming community has moved on to more recent instructions sets, after many years I still get queries about Quexal, so I've decided to release it as freeware, as it may be useful for learning SIMD coding. However, simply releasing the last published version of Quexal was not enough, and this was an opportunity to spend some time on this pet project of mine and improve it.

So here you have it, an updated version of Quexal for free! Just go to the download section to get it.

MMX / iSSE instructions can greatly enhance the performance of the following applications: multimedia (audio/video), communications, DSP kernels, 2D and 3D graphics, image processing and speech recognition.
But current compilers do not support these instructions. You have to learn all those instructions sets, then painfully code in plain assembly, then discover that achieving the maximum performance requires deep knowledge of the processors' microarchitectures, and finally that debugging and modifying your code is a nightmare.
Now there is a better way: Quexal, a development environment aimed at MMX / iSSE programmers.
Here is how Quexal will help you get the job done quickly and easily:

Now you can build State-of-the-Art applications quickly and easily with Quexal!
