GOLDELOX Processor
1. Description
The GOLDELOX 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, EVE (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.
All of the display 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.
4D Systems software development IDE called
Workshop 4 is FREE and there are no licensing
requirements.
The GOLDELOX offers one of the most flexible
embedded graphics solutions available.
