picoJava™-I is a small, flexible microprocessor core designed to directly execute Java™ bytecodes. The primary goal of this core is to enable chips with the best price/performance solution for running Java applications on a broad class of devices. The picoJava-I core provides between five to twenty times better performance than other means of Java execution. The design of picoJava-I is influenced by many characteristics of the Java language and the Java Virtual Machine™. These influences are discussed, the microarchitecture is presented, and the resulting performance is described.
