Quexal description
Quexal - Visual tool for writing MMX / iSSE code

Quexal offers you MMX/SSE instructions that 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.

Now there is a better way: Quexal, a development environment aimed at MMX/iSSE programmers.

Here are some key features of "Quexal":

· flatten the learning curve! you can work with well understood concepts, such as variables and common operations, instead of registers and cryptic MMX/SSE opcodes;
· take it easy! its custom designed graphical interface guides you step by step, displaying only relevant options;
· work faster! the compiler optimizes source code into optimally scheduled MMX/SSE assembly code that can be directly pasted into any other development environment, thus taking the optimization phase, the most time-consuming and error prone one, out of the development cycle;
· save an upgrade! you can use MMX and iSSE instructions even if your compiler does not support them, as the bytecode compiler turns source instructions directly into machine language; Quexal supports the Microsoft Visual C++, Borland C++ Builder and Borland Delphi compilers;
· bug killer! includes a visual Debugger that re-arranges source code in a graph showing dependency bonds among instructions; you can enter source values and analyze what the instructions defined in source code do, and therefore easily detect troublesome spots;
· become a code guru - instantly! the optimized code is as good as that written by world class programmers, but no knowledge of micro architectural designs is required;
· maintaining code? no problem! you can modify the source code in the Quexal environment and then optimize it again, instead of changing MMX/iSSE code listings.


Limitations:

· Some features are disabled.
