Abstract
A dynamic binary translator 19 converts a subject program 17 into target code 21 on a target processor 13. For a multi-threaded subject environment, the translator 19 provides a global token 501 common to each thread 171, 172, and one or more sets of local data 502, which together are employed to coordinate access to a memory 18 as a shared resource. Adjusting the global token 501 allows the local datastructures 502a,b in each thread to detect potential interference with the shared resource 18.
