1. A method for operating a digital system, wherein the digital system has a processor with a virtual machine environment for interpretively executing instructions, comprising the steps of: a) receiving a sequence of instructions for execution by the virtual machine; b) determining if a certain type of iterative sequence is present by examining the sequence of instructions; c) if the certain type of iterative sequence is present, replacing the iterative sequence with a proprietary code sequence; d) executing a portion of the sequence of instructions in an interpretive manner; and e) executing the proprietary code sequence directly by acceleration circuitry.
