Abstract :
The Java Virtual Machine (JVM) is the cornerstone of Java technology, and its efficiency in executing portable Java bytecodes is crucial for the success of this technology. Interpretation, just-in-time (JIT) compilation and hardware realization are well-known solutions for JVM, and previous research has proposed optimizations for each of these techniques. However, each technique has its pros and cons and may not be uniformly attractive for all hardware platforms. Instead, an understanding of the architectural implications of JVM implementations with real applications can be 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). Towards this goal, this paper examines architectural issues, from both the hardware and JVM implementation perspectives. It specifically explores the potential of a smart JIT compiler strategy that can dynamically interpret or compile based on associated costs, investigates the CPU and cache architectural support that would benefit JVM implementations, and examines the synchronization support for enhancing performance, using applications from the SpecJVM98 benchmarks
