GOLDELOX processor

The GOLDELOX processor is a custom embedded graphics controller designed to interface with many popular OLED and LCD display panels. Powerful graphics, text, image, animation and countless more features are built right inside the chip. It offers a simple plug-n-play interface to many 8bit 80-Series colour LCD and OLED displays.

The chip is designed to work with minimal design effort and all of the data and control signals are provided by the chip to interface directly to the display. Simply choose your display and interface it to the GOLDELOX on your application board. This offers enormous advantage to the designer in development time and cost saving and takes away all of the burden of low level design.

The GOLDELOX belongs to a family of processors powered by a highly optimised soft core virtual engine, E.V.E. (Extensible Virtual Engine). EVE is a proprietary, high performance virtual processor with an extensive byte-code instruction set optimised to execute compiled 4DGL programs. 4DGL (4D Graphics Language) was specifically developed from ground up for the EVE engine core. It is a high level language which is easy to learn and simple to understand yet powerful enough to tackle many embedded graphics applications.

The device offers modest but comprehensive I/O features and can interface to SPI, serial, analogue, digital, buttons, joystick and Dallas 1-wire devices. Provision is also made for creating complex sound effects for audible user feedback with an extended RTTTL tone generator.

A basic system font is included, and unlimited customisable fonts with fixed or proportional spacing can be created using the Workshop 4 IDE. The chip-resident display driver libraries implement and share the same high-level functional interface. This allows your GUI application to be portable to different display controller types.

The 4D Workshop4 IDE is FREE and there is no licensing requirement.
