摘要： Disclosed are techniques for simulating a multiprocessor system is disclosed. Aspects of the present invention are based on such an observation that most memory accesses from different simulated processors do not conflict, and therefore the conservative policy for performing synchronization of all the memory accesses can waste a large amount of processing time. By identifying possibly conflicting memory accesses and only performing synchronization of these memory accesses, the synchronization cost can be reduced considerably. Since the function simulator is able to operate faster and to perform the same memory accesses, the possibly conflicting memory accesses can be identified by first executing the function simulator.

The compiler includes operation modules for calling DLLs during streaming program execution; association table generating units for generating association tables according to user-defined rules, where the association table includes entries indicating (i) stream branches of the streaming program and (ii) an operation module corresponding to the stream branches; and a trigger generating unit for generating a trigger based on user-defined rules, where the trigger generating unit (i) determines which conditions for loading and unloading DLLs fit the streaming program, (ii) matches these conditions to a particular stream branch to identify a matched stream branch, and (iii) sends out triggering signals indicating the matched stream branch. This invention also provides a corresponding method and controller.
