Abstract
A simulation technique that handles accesses to a frame of memory via a proxy object provides improved throughput in simulation environments. The proxy object, if present, processes the access at a head of a linked list of frames. If a check frame is not inserted in the list, the memory frame handles the request directly, but if a check frame is inserted, then the check operation is performed. The check frame can be a synchronization frame that blocks access to a memory frame while the check frame is present, or the check frame may be a breakpoint, watch or exception frame that calls a suitable handling routine. Additional check frames may be chained between the interface and the memory subsystem to handle synchronization, breakpoints, memory watches or other accesses to or information gathering associated with the memory frame.
