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 an MSP430 toolchain in a cycle accurate way.

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>
|
<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>
|
<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>
