• Easily add Windows user interface to DSP app
• Also supports C std. I/O from DSP
• Access any Windows feature
• Ready-written drivers for many DSP boards
• Simple, high-level API

The user-interface parts of your application are written using standard Windows tools like Visual C++ or Visual Basic. That gives your DSP code access to any Windows feature, from menus and dialogs right up to OLE, DirectX and Winsock networking. 3L provides a DLL that allows your host program to download code to the DSP and then communicate with it. All this functionality is accessible from easy-to-use C++ classes that build on Microsoft's foundation classes (MFC).

On the target side, a library of C-callable functions is provided that allows the DSP to exchange messages with the host-side code. This library integrates with 3L's Parallel C programming environment to allow the host to signal semaphores on the DSP when interesting user-interface events occur (e.g., mouse clicks, menu commands).
