GOLDELOX PROCESSOR
6. 4DGL - Software Language
The GOLDELOX graphics processor 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-
machine 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.
4DGL is a graphics oriented language allowing
rapid application development, and the syntax
structure was designed using elements of popular
languages such as C, Basic, Pascal and others.
Programmers familiar with these languages will
feel right at home with 4DGL. It includes many
familiar instructions such as IF..ELSE..ENDIF,
WHILE..WEND, REPEAT..UNTIL, GOSUB..ENDSUB,
GOTO, PRINT as well as some specialised
instructions SERIN, SEROUT, GFX_LINE,
GFX_CIRCLE and many more.
For detailed information pertaining to the 4DGL
language, please refer to the following documents:
“4DGL-Programmers-Reference-Manual.pdf”
“GOLDELOX-4DGL-Internal-Functions.pdf”
To assist with the development of 4DGL
applications, the Workshop 4 IDE combines a full-
featured editor, a compiler, a linker and a
downloader into a single PC-based application. It's
all you need to code, test and run your
applications.
7. In Circuit Serial Programming ICSP
The GOLDELOX processor can be re-programmed
with the latest PmmC configuration for updates
and future proofing. The chip-level configuration is
available as a PmmC (Personality-module-micro-
Code) file and the programming must be
performed over the serial interface. The chip-
resident internal 4DGL functions are part of the
GOLDELOX PmmC configuration file so please
check regularly for the latest updates and
enhancements.
A PmmC file can only be programmed into the
device via its serial port and an access to this must
be provided for on the target application board.
This is referred to as In Circuit Serial Programming
(ICSP). Diagram below provides a typical
implementation for the ICSP interface.
ICSP Interface
The PmmC file is programmed into the device with
the aid of Workshop 4, the 4D Systems IDE
software (See Section 11). To provide a link
between the PC and the ICSP interface, a specific
4D Programming Cable is required and is available
from 4D Systems.
Using a non-4D programming interface could
damage your display, and void your Warranty.
Note: The GOLDELOX chip is shipped blank and it
must be programmed with the PmmC
configuration file.
