sEc: A Portable Interpreter Optimizing Technique for Embedded Java Virtual Machine
K. Venugopal, Geetha Manjunath, Venkatesh Krishnan · 2002
This paper describes a radical approach to aggressively optimize an embedded Java virtual machine interpretation in a portable way. We call this technique Semantically Enriched Code (sEc). The sEc technique can improve the speed of a JVM by orders of magnitude. The sEc technique adapts an embedded Java virtual machine to the demands of a Java application by automatically generating an enhanced virtual machine for every application. The bytecode set of the virtual machine is augmented with new application-specific opcodes, enabling the application to achieve greater performance. Aggressive static or offline optimizations are done to ensure tight coupling between the Java application, Java virtual machine and the underlying hardware. sEc makes an embedded Java virtual machine become a domain specific Java virtual machine – a versatility not possible with the hardware.
