EMBEDDED GRAPHICS PROCESSOR LCD-OLED ONE-CHIP SOLUTION

The GOLDELOX-GFX Graphics Processor is an exciting new concept introduced by 4D Labs to the industry. It is completely configurable and will interface with many popular LCD and OLED displays and implements a set of integrated high-level graphics and I/O functions controlled by E.V.E.(Extensible Virtual Engine).

EVE is a proprietary, high performance virtual processor implemented across a variety of architectures to provide a single unified platform. This enables the same application code developed for the GOLDELOX-GFX to run on any other 4D custom processor (with EVE implementation) such as the PICASO-GFX. You will never again need to worry about selecting third party C source libraries, or which microcontroller to use. Just simply choose your display, interface it to the GOLDELOX-GFX on a PCB and add some I/O depending on your application.

Finally select the PmmC file that matches your display driver IC (e.g. GOLDELOX-GFX-1339.pmmc for the SSD1339 display IC from Solomon) and download this into the GOLDELOX-GFX chip via the serial port and you have a powerful single chip graphics user interface solution. You are now ready

to write your code in 4DGL (a high level 4D Graphics Language) using the 4D Workshop (editor and compiler) and save weeks even months of development time on your next embedded graphics project. 4DGL is a graphics oriented language allowing the developer to write applications in a high level language, syntax similar to popular languages such as BASIC, C and Pascal.

In simple applications, the GOLDELOX-GFX may be all you need as its modest but comprehensive I/O features can interface to serial, analogue, digital, sound generation and Dallas 1-wire devices. In more complex applications, you can offload most of your graphics overhead to the GOLDELOXGFX and just send serial commands to perform the required actions from your favourite host processor.

All of the LCD and OLED built-in driver libraries implement and share the same high-level function interface. This allows your GUI application to be portable to different display controller types.

The software development tools such 4DGL Workshop and Graphics Composer is FREE and there are no licensing requirements.

Your development is supported by an ever increasing range of modules and prototyping boards to provide a rapid aid to development.

The GOLDELOX-GFX is available in a tiny 28 pin QFN package.
