ABSTRACT:
Improved techniques for invocations of native methods in Java computing environments are disclosed. The techniques can be implemented in Java computing environments to facilitate efficient use of methods (functions or subroutines) written in programming languages other than Java (e.g., C, C++, etc.). As such, the techniques are highly suitable for use by virtual machines operating with relatively less memory and/or computing power (e.g., embedded systems). A lightweight native method invocation interface can be implemented to provide direct access to Java parameters on the execution stack. In addition, the lightweight native method invocation can include macro instructions that operate efficiently to convert the Java parameters into native parameters. Thus, the lightweight native method invocation can significantly reduce the overhead associated with conventional Java native method invocation techniques. As a result, performance of virtual machines, especially those operating with relatively less memory and/or computing power, can be improved.
