Architectural Support for Efficient Java Runtime Systems


An understanding of the architectural implications of the Java Virtual Machine (JVM) implementations is crucial to the development of enabling technologies for efficient Java runtime system development on a wide range of platforms from resource-rich servers to resource-constrained hand-held/embedded systems. This talk will present results of workload characterization studies that unveil architectural issues from both hardware and software JVM implementation perspectives. The potential of a smart Just-In-Time (JIT) compiler strategy that can dynamically interpret or compile based on associated costs, and the usefulness of decoupling translate and execution phases of Java execution are explored. Techniques to allow instruction level parallelism (ILP) in Java Processors will be discussed.
