<!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> <br> <h1>Introduction</h1> The openMSP430 is a synthesizable 16bit microcontroller core written in Verilog. It is compatible with Texas Instruments' <b><a href="http://www.ti.com/litv/pdf/slau049f">MSP430 microcontroller family</a></b> and can execute the code generated by any MSP430 toolchain in a near cycle accurate way.<br><br> The core comes with some peripherals (<b>16x16 Hardware Multiplier, </b>Watchdog, GPIO, TimerA, generic templates) and most notably with a two-wire <b>Serial Debug Interface</b> supporting the<b> <a href="http://sourceforge.net/apps/mediawiki/mspgcc/index.php?title=MSPGCC_Wiki" target="_blank">MSPGCC</a> GNU Debugger</b> (GDB) for in-system software debugging. <br><br> While being fully FPGA friendly, this design is also particularly suited for ASIC implementations (typically mixed signal ICs with strong area and low-power requirements).<br> In a nutshell, the openMSP430 brings with it:<br> <ul> <li>Low area (8k-Gates), without hidden extra infrastructure overhead (memory backbone, IRQ controller and watchdog timer are already included).</li> <li>Excellent code density.</li> <li>Good performances.</li> <li>Build-in power and clock managment options.</li> <li>Multiple time <span style="font-weight: bold;">Silicon Proven</span>.<br> </li> </ul> <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" cellpadding="0" cellspacing="4"> <tbody><tr> <td width="35"><br> </td> <td bgcolor="#d0d0d0" width="3"><br> </td> <td width="15"><br> </td> <td> <code>svn export http://opencores.org/ocsvn/openmsp430/openmsp430/trunk/ openmsp430</code> </td> </tr> </tbody></table> <br> <h3>ChangeLog</h3> <ul> <li>The <a href="http://opencores.org/websvn,filedetails?repname=openmsp430&path=/openmsp430/trunk/ChangeLog_core.txt">Core's ChangeLog</a> lists the CPU updates.</li> <li>The <a href="http://opencores.org/websvn,filedetails?repname=openmsp430&path=/openmsp430/trunk/ChangeLog_tools.txt">Tools' ChangeLog</a> lists the Software development tools updates.</li> <li>Subscribe to the following <a href="http://opencores.org/websvn,rss?repname=openmsp430&path=/openmsp430/&isdir=1">RSS</a> feed to keep yourself informed about ALL updates. </li></ul> <br> <h3>Documentation</h3>Being fully compatible with the original MSP430 architecture, TI's official documentation is applicable: <a href="http://www.ti.com/lit/ug/slau049f/slau049f.pdf">SLAU049F.PDF</a><br><br> In addition, the openMSP430 online documentation is also available in <a href="http://opencores.org/websvn,filedetails?repname=openmsp430&path=%2Fopenmsp430%2Ftrunk%2Fdoc%2FopenMSP430.pdf" title="openMSP430 PDF Doc.
