A low-cost RISC microprocessor dedicated to executing Java -based bytecodes without the need for a interpreter or JIT compiler.
picoJava directly executes the Java Virtual Machine instruction set. As a result, Java software applications are up to 3 times smaller in code size and up to 5 times faster–thus reducing memory requirements–and 20 times faster than Java interpreters running on standard CPUs.
It does not include any memory or I/O interfacelogic. Rather, developers can add their own logic to customize memory and an interface.
