DIABLO16 PROCESSOR
4D SYSTEMS
DIABLO16 Processor
1. Description
The DIABLO16 Processor is the latest addition to
the 4D Systems processor range, providing more
power, more FLASH, more RAM and more features
than the PICASO Processor.
The DIABLO16 Processor is a custom embedded
4DGL graphics controller designed to interface
with many popular OLED and LCD display panels.
With its powerful graphics, text, image, and
animation abilities built-in, along with numerous
more features makes the Diablo16 a single chip
solution for a wide variety of LCD and OLED display
solutions.
The DIABLO16 offers a simple plug-n-play interface
to many 16-bit 80-Series colour LCD and OLED
displays, and is designed to work with minimal
design effort as all of the data and control signals
are provided by the chip to interface directly to
the display. 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 DIABLO16 belongs to 4D Systems 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 processor offers a comprehensive set of I/O
features and can interface to SPI, I2C, serial,
digital, and analog devices, and provides a wealth
of features such as PWM, Quadrature, PulseOut
and Pin Counter functions. Provision is also made
for a dedicated PWM audio output that supports
audio WAV files and complex sound generation.
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
Workshop4 is FREE and there are no licensing
requirements.
