Abstract
One embodiment of the present invention provides a system that facilitates faster execution of code on a memory-constrained computing device that has fast on-chip RAM, wherein the fast on-chip RAM is located on a processor chip, but is not cache memory. The system operates by copying a compiled method from an object heap to the fast on-chip RAM on the memory-constrained computing device. Additionally, the system updates an execution pointer to point to the compiled method in the fast on-chip RAM, wherein the execution pointer can also point to a compiled method in the object heap or an interpreted method in the object heap.
