Abstract

One embodiment of the present invention provides a system for increasing the performance of a platform-independent virtual machine in executing a sequence of platform-independent codes (pi-codes) generated by a high-level language compiler The system operates by first obtaining a pi-code to be executed by the platform-independent virtual machine. Next, the system locates a sequence of native code instructions that, when executed, will perform the action required by the pi-code. The system then executes the sequence of native code instructions. After the code has been executed, the system stores a copy of the sequence of native code instructions associated with the pi-code in a cache. Finally, if the pi-code defines a loop, the system saves a pointer to a beginning of the loop within the cache which, when used as a reference during execution, will cause the loop to be executed from the cache rather than from the pi-code.
