Abstract

See full text

Application programs compiled for a first, 'source', computer are translated, from their object form, for execution on a second, 'target', computer. The translated application programs are linked or otherwise bound with a translation of the source computer system software. The translated system software operates on the image of the source computer address space in the target computer exactly as it did in the source computer. The semantics of the source computer system software are thus preserved identically. In addition, a virtual hardware environment is provided in the target computer to manage events and to deal with differences in the address space layouts between the source and target computers.
