<h1>Introduction</h1>
The openGFX430 is a synthesizable Graphic controller written in Verilog and tailored
for the <a href="http://opencores.org/project,openmsp430">openMSP430</a> core.
<br><br>
An example implementation based on the
<a href="http://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&No=941">DE0-Nano-SoC</a> and
<a href="http://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&No=892">LT24 daughter board</a> from Terasic
can be found in the openMSP430 FPGA section (<a href="http://opencores.org/websvn,listing?repname=openmsp430&path=%2Fopenmsp430%2Ftrunk%2Ffpga%2Faltera_de0_nano_soc%2F#path_openmsp430_trunk_fpga_altera_de0_nano_soc_">see here</a>).
