ABSTRACT:
In executing a new method, a hardware processor loads the execution environment on a stack in the background and indicates what portion of the execution environment has been loaded so far, e.g., simple one bit scoreboarding. Thus, the hardware processor tracks the information in the execution environment loaded on the stack. The hardware processor tries to execute the bytecodes of the called method as soon as possible, even though the stack is not completely loaded. If accesses are made to variables already loaded, overlapping of execution with loading of the stack is achieved. Thus, execution and loading continue until information in the execution environment needed for the execution is not on said stack as indicated by said tracking.
