Abstract: A trace-data-processing device for reconstructing an execution flow of a program performed by a source device under test or under observation, herein DUT, using at least one source-specific trace-data stream is disclosed. The trace-data-processing device comprises a trace-data-processing unit, which is configured to identify in the trace-data stream at least one instruction-synchronization message and branch messages. Moreover, the trace-data-processing device is configured to generate runtime-information data indicative of an at least partial reconstruction of the execution flow, using the identified trace messages, a pre-defined branch identifier allocated to each branch instruction address in the program that is associated with a direct branch instruction and pre-stored reconstruction information stored in a reconstruction memory.

Abstract: An event-processing unit for processing tokens associated with a state or state transition, herein also referred to as an event, of an external device is disclosed. The EPU allows token-processing schemes, in which the processing of incoming tokens and the further handling of a processing result by the EPU are determined not only by the token identifier, but also by the payload data of the incoming token or by data in the data memory. A flag-processing capability of a processing-control stage allows applying flag-processing operations such as logical operations to data obtained as a processing result of an ALU-processing operation. The result of these operations determines a subsequent handling of ALU-result data by the EPU. Thus, whether or not the ALU-result data is written to the data memory also influences the processing of any subsequent incoming tokens for which that data is used in the ALU-processing operation.
