Abstract

A tracking device for a data processing system comprising at least one central data processing unit and its memory, allowing exchanges between said processing unit and its memory, and knowing, from certain signals generated by said processing unit, the successive operations carried out by the processing unit and being characterized in that they include: - a storage device connected to the processing unit considered and which receives from it, for each memory operation performed by the processing unit, a tracking information constituted, on the one hand, by the direction and working mode signals transmitted by the processing unit to its memory and, on the other hand, of the indicator signals that define the type of operation of the memory; - a logic addressing unit that receives, on the one hand, the signals that define the type of memory operation sent by said processing unit and, on the other hand, the control signals from the control unit of the tracking device that indicate the required work mode of the storage device and, if necessary, the type of operation to be stored. Said logical addressing unit indicates to the storage device either the address where said tracking device should be stored, or the address of the word to be transferred to the control unit.
