Sie stehen damit in Konkurrenz zu <a href="Java_Virtual_Machine" title="Java Virtual Machine">Java Virtual Machines</a> wie <a href="Interpreter" title="Interpreter">Interpretern</a> und <a href="Just-in-time-Compilierung" class="mw-redirect" title="Just-in-time-Compilierung">Just-in-time</a>-<a href="Compiler" title="Compiler">Compilern</a>.

</p><p>Die meisten Java-Prozessoren existieren als <a href="IP-Core" title="IP-Core">IP-Cores</a> und werden in <a href="Field_Programmable_Gate_Array" title="Field Programmable Gate Array">FPGAs</a> oder <a href="Anwendungsspezifische_integrierte_Schaltung" title="Anwendungsspezifische integrierte Schaltung">ASICs</a> eingesetzt.

</p><p>Beispiele von Java-Prozessoren sind:

</p>

<ul><li><a href="PicoJava" title="PicoJava">picoJava</a> von <a href="Sun_Microsystems" title="Sun Microsystems">Sun Microsystems</a></li>

<li>PSC von Patriot Scientific</li>

<li>„Jazelle“-Erweiterung für <a href="ARM-Architektur" title="ARM-Architektur">ARM-Prozessoren</a>, zu finden etwa in vielen Java-fähigen Mobiltelefonen.</li>

<li>JOP (Java Optimized Processor) – ein Java-Bytecode-Prozessor, der als <a href="Open_Source" title="Open Source">Open Source</a> für <a href="Field_Programmable_Gate_Array" title="Field Programmable Gate Array">FPGAs</a> zur Verfügung steht.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup></li></ul>

<p>Der <a href="Atmel_AVR32" title="Atmel AVR32">Atmel AVR32</a> kann Bytecode direkt in Hardware ausführen, ist jedoch kein vollständiger Java-Prozessor.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup>
