Java Chips

It used to be thought that Java performance could be brought up to or beyond that of native code on current CPUs by the implementation of the VM in hardware. At that point, the term “virtual” will no longer be accurate. The JVM was designed to be implemented in hardware eventually, and the Java chip should be quite a bit faster for the bytecodes that can be easily implemented in hardware.

Unfortunately, there are bytecodes that require extensive processing to execute (such as declaring a new object) and are not easily implemented in hardware. In some Java software, only 15 percent of the processing is bytecode interpretation by the VM. For these reasons, and because the first Java chips produced were too big and ran too hot, it seems that most plans for Java chips have been cancelled.
