Abstract:
Additional memory for holding marking tags is used for providing additional information regarding states acquired by an emulator during tracing for dequeueing. The marking tags are determined according to a predetermined coding scheme, loaded in a marking memory, and acquired during tracing along with the fetched instruction states. The combination of addresses, data, status, and the additional marking tags is converted into a list of states which correspond to the test program executed by the target processor means.
