A CPU chip from Sun that executes Java bytecode natively. It is based on Sun's picoJava architecture and is used in a wide range of devices from small, handheld appliances to desktop network computers. The picoJava chip contains the core architecture of the Java Virtual Machine and can be built into cellphones and other handheld devices. The microJava chip includes the picoJava core plus memory, I/O and other control functions and is targeted towards controllers, network-based devices and consumer products. The first model was introduced in late 1998. The UltraJava chip is targeted for desktop use and incorporates some of Sun's 3D graphics processing capabilities used in its UltraSPARC machines.
