GOLDELOX GRAPHICS 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 Labs software development IDE called Workshop4
is FREE and there are no licensing requirements.
The Goldelox offers one of the most flexible
embedded graphics solutions available.

DESCRIPTION
Display Read strobe signal. Goldelox asserts this signal LOW when reading data
from the display. Connect this pin to the Read (RD) signal of the display.
Display Write strobe signal. Goldelox asserts this signal LOW when writing data to
the display. Connect this pin to the Write (WR) signal of the display.
Internal voltage regulator filter capacitor. Connect a 4.7uF to 10uF capacitor from
this pin to Ground.
Display Register Select.
LOW: Display index or status register is selected.
HIGH: Display GRAM or register data is selected.
Connect this pin to the Register Select (RS or A0 or C/D or similar naming
convention) signal of the display.
Ground.
System Clock input 1 of a 12MHz crystal.
System Clock input 2 of a 12MHz crystal.
SPI device Chip Select. Connect this pin to the Chip Enable (CE or CS) signal of the
external SPI device (SD/SDHC memory card, Serial Flash chip, etc.).
Display Chip Select. Goldelox asserts this signal LOW when accessing the display.
Connect this pin to the Chip Select (CS) signal of the display.
Display RESET. Goldelox initialises the display by strobing this pin LOW. Connect this
pin to the Reset (RES) signal of the display.
