DATA VALUE COHERENCE IN COMPUTER SYSTEMS

摘要

The invention concerns the general data value problem, and especially the residence problem in a computer system when executing program code translate d from a source code representation (10) into a target code representation (30 ). A basic idea of the invention is to associate references to target data valu e containers (40) in the target code with corresponding address information of original data value containers (20) of the source code during program code translation, and store information related to target code instructions together with associated address information of original data value containe rs at execution of target code to uphold a data value view (50) of the original source code representation. In this way, tracking of data values of original source code (10) at execution of translated target code (30) in a target system is supported in a highly efficient manner.
