<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <title>openMSP430 Overview</title> </head> <body> <h1>Introduction</h1> The openMSP430 is a synthesizable 16bit microcontroller core written in Verilog. It is compatible with Texas Instruments' MSP430 microcontroller family and can execute the code generated by an MSP430 toolchain in a cycle accurate way. <br /><br /> The core comes with some peripherals (16x16 Hardware Multiplier, GPIO, TimerA, generic templates) and a Serial Debug Interface for in-system software development. <h1>Download</h1> <h3>Design</h3> The complete tar archive of the project can be downloaded <a href="http://www.opencores.org/download,openmsp430">here</a> (OpenCores account required).<br /> <br /> The following SVN command can be run from a console (or <a href="http://www.syntevo.com/smartsvn/index.html">GUI</a>): <br /><br /> <table border="0" cellspacing="4" cellpadding="0"> <tr> <td width="35"></td> <td bgcolor="#d0d0d0" width="3"></td> <td width="15"></td> <td> <code>svn export http://opencores.org/ocsvn/openmsp430/openmsp430/trunk/ openmsp430</code> </td> </tr> </table> <br /><br /> To keep yourself informed about project updates, you can subscribe to the following <a href="http://opencores.org/websvn,rss?repname=openmsp430&path=/openmsp430/&isdir=1">RSS</a> feed. <br /><br /> <h3>Documentation</h3> The online documentation is available as <a href="usercontent,doc,1283025143" title="openMSP430 PDF Doc.
