Abstract
Techniques for simulating a multiprocessor system. 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.
