Abstract

A method of dynamic real time translation of first program code written for a first programmable machine into second program code (target code) for running on a second programmable machine employing run time generation of an intermediate representation of the first program code. The intermediate representation is generated to include a combination of register objects and expression objects. Register objects represent abstract registers that provide a representation of the state of the first programmable machine based on expected effects of the instructions within the first program code, while expression objects represent elements, such as operations or sub-operations, of the instructions in the first program code. In the intermediate representation, a branched tree-like network is formed in which each register object serves as a basic root of the network and references expression objects to which they relate either directly or indirectly through references from other expression objects.
