A CPU (Central Processing Unit) that runs the JVM (Java Virtual Machine) byte code directly in hardware or firmware. It does not require a software JVM. It have
have software assist to handle some of the more complicated byte code instructions like new. Sun made Java silicon chips call PicoJava. It ran too hot, (took too much electricity) and the
project was discontinued, though I think they took another run at it with the Picojava II. Over a dozen companies now make Java cpus for
the embedded market. The advantage is compact code and high speed. Compact code is especially important in
low-cost battery-powered devices.
