Abstract

A method for evaluating sensor data for a value document includes a memory and a multi-core processor arranged to access the memory. A management sub-group of the cores comprises at least one of the cores, and at least one evaluation subgroup of the cores comprises at least one other of the cores. The management subgroup manages the memory regarding the storing of at least the sensor data and generates evaluation information for carrying out the evaluation. At least one evaluation subgroup carries out at least one part of the evaluation in dependence on the evaluation information and stores the result in the memory.

First claim

The invention claimed is:

1. A device for evaluating sensor data for a value document, comprising:
a memory for storing at least the sensor data for the value document;
a multi-core processor having at least two cores; and
software which comprises a management component and an evaluation component for carrying out evaluations of the sensor data;
wherein the device is devised such
that a management subgroup of the cores is formed having at least one of the cores and at least one evaluation subgroup of the cores having at least one other of the cores,
that the management component for its execution is associated with the management subgroup, and
that the evaluation component for its execution is associated with the at least one evaluation subgroup,

wherein upon execution by the management subgroup, the management component manages the memory with regard to the storing of at least the sensor data and generates evaluation information for carrying out the evaluation;
wherein upon execution by the at least one evaluation subgroup in dependence on the evaluation information, the evaluation component carries out at least one part of the evaluation and stores a result in the memory; and
wherein each of the cores of the management subgroup and each of the cores of the at least one evaluation subgroup are managed by a same single operating-system entity.

2. The device according to claim 1 , wherein both the cores of the management subgroup and the cores of the at least one evaluation subgroup have access to the memory.

3. The device according to claim 1 , in which the management subgroup comprises exactly one core.

4. The device according to claim 1 , in which the at least one evaluation subgroup comprises at least two cores.

5. The device according to claim 1 , in which the management component is devised such that upon execution by the management component by the management subgroup, signals of at least one other device are received and/or signals to at least one other device are sent and preferably in dependence on at least one result of the evaluation at least one signal is emitted by means of which the further processing of the value document is controllable.

6. The device according to claim 1 , in which the evaluation information contains information about partial evaluations, which are partial portions of the evaluation of the sensor data, which are to be carried out by the evaluation component upon execution by the at least one evaluation subgroup, and
in which upon execution by the at least one evaluation subgroup in dependence on the evaluation information the evaluation component carries out the partial evaluations and stores the results of these in the memory.

7. The device according to claim 6 , in which the management component is devised such that the evaluation information has at least one list of evaluation descriptors which describe partial evaluations, and the evaluation component is devised to carry out the partial evaluations on the basis of the list and to store the results in the memory.

8. The device according to claim 1 , in which at least one of the partial evaluations employs at least one result of a previously carried out partial evaluation which is preferably stored in the memory.

9. The device according to claim 1 , which is further designed such that upon execution of the software in the memory, a data structure is supplied in which for a respective value document results of the partial evaluations are stored.

10. The device according to claim 1 , in which priorities are assigned to the partial evaluations and these are taken into consideration upon the execution of the evaluation component.

11. The device according to claim 1 , in which at least two evaluation subgroups are formed, preferably with the same number of cores, and for each of the evaluation subgroups the management component stores evaluation information associated with the respective evaluation subgroup in the memory, and each of the evaluation subgroups upon execution of the evaluation component employs the evaluation information associated with it.

12. The device according to claim 1 , in which the management component is devised to store sensor data sets for different value documents in the memory and to store evaluation information for each of the sensor data sets in the memory, so that the evaluation component upon execution by one of the evaluation subgroups according to the evaluation information associated with the evaluation subgroup and the sensor data set evaluates the sensor data of the sensor data set at least partially and stores the results for the sensor data set in the memory.

13. The device according to claim 1 , in which the software comprises at least one auxiliary component, wherein the device is further designed such that an auxiliary subgroup of the cores is formed, and the auxiliary component upon execution by the auxiliary subgroup executes pre-specified operating-system tasks.

14. An apparatus for processing value documents, having a feeding device for feeding singled value documents, an output device for outputting processed value documents, a transport device for transporting singled value documents of the feeding device to the output device, a sensor device for capturing physical properties of the transport device of transported value documents and forming sensor data for the respective value document, and an evaluation device connected to the sensor device for evaluating the sensor data of the sensor device according to claim 1 .

15. The apparatus according to claim 14 , which further has a machine control device connected to the evaluation device which drives the transport device in dependence on the result of the evaluation of the sensor data.

16. The device according to claim 1 , wherein the evaluation information includes evaluation descriptors describing functions to be executed in the evaluation of the sensor data.

17. A method for evaluating sensor data for a value document, comprising:
employing a memory and a multi-core processor which can access the memory, the multi-core processor including a plurality of cores, wherein a management subgroup of the cores comprises at least one of the cores and at least one evaluation subgroup of the cores comprises at least one other of the cores,
managing by the management subgroup the memory with regard to storing of at least the sensor data and generating by the management subgroup evaluation information for carrying out the evaluation, and
carrying out by the at least one evaluation subgroup, in dependence on the evaluation information at least one part of the evaluation and storing a result in the memory,
wherein each of the cores of the management subgroup and each of the cores of the at least one evaluation subgroup are managed by a same single operating-system entity.

19. The method according to claim 17 , in which the at least one evaluation subgroup comprises at least two cores.

20. The method according to claim 17 , in which by means of the management subgroup, signals of at least one other device are received and/or signals to at least one other device are sent and preferably in dependence on at least one result of the evaluation at least one signal is emitted by means of which the further processing of the value document is controllable.
