摘要： A system and method for modifying an information unit, the method includes the following stages: (i) receiving, over a first bus, a request to initiate a snooping type atomic operation associated with at least one information unit located at a first address of a memory module; (ii) providing the information unit over the first bus; (iii) attempting to complete the snooping type atomic operation of an updated information unit; and (iv) defining the atomic operation as a failed atomic operation if during at least one stage of receiving, providing and attempting, the first address was locked as a result of a locking type atomic operation.

摘要： A method and apparatus non-intrusive tracing. The method includes: counting selected events by multiple counters; sampling the multiple counters to retrieve multiple counter values in response to predefined triggering events; receiving additional trace information that comprises at least one program counter value, and outputting, as a trace information, at least one of the multiple counters values and the additional trace information.

摘要： A data processing device for executing a program is described. The program comprises one or more instruction groups and one or more predicates, each instruction group comprising one or more instructions. The data processing device comprises a processing unit and a trace unit connected to or integrated in the processing unit. The trace unit generates a predicate trace for tracing the values of the one or more predicates. The processing unit executes, in each of a series of execution periods, one of the instruction groups and updated the values of none, one, or more of the predicates in dependence on the respective instruction group. The trace unit appends the updated values of the none, one, or more predicates to the predicate trace and does not append any non-updated values of the predicates.A method of reporting predicate values and a data carrier are also disclosed.
