Abstract

The invention relates to a method for operating a multiprocessor system, especially in conjunction with a medical imaging system. The invention also relates to a medical imaging device which is designed to perform this method. The multiprocessor system in this case has at least two processing units, at least one control unit and operations which can be allocated to the processing units. Data provided from an input is processed by the processing unit and made available at an output. The at least one control unit enhances the named data with control data, which defines an allocation of the data to the respective operations for the purposes of processing.

Claims

1-18. -18. (canceled)

19. A method for operating a multiprocessor system comprising a plurality of processing units, comprising:

assigning a control unit to the processing units;

assigning a plurality of operation algorithms to the processing units respectively for processing a plurality of data;

allocating the data to the operation algorithms respectively;

inserting a plurality of control data to the data respectively by the control unit; and

defining the allocation of the data based on the inserted data.

20. The method as claimed in the claim 19, wherein the allocation of the data is defined by a predetermined sequence.

21. The method as claimed in the claim 19, wherein the control unit assigns the operation algorithms to the processing units.

22. The method as claimed in the claim 19, wherein the data is sequentially or parallel processed based on the allocation of the data.

23. The method as claimed in the claim 19, wherein a further processing unit is dynamically added and is assigned to a further operation algorithm for processing the data.

24. The method as claimed in the claim 19, wherein the control data is inserted to the data during or after processing for specifying a renewed or repeated allocation of the data to the operation algorithms.

25. The method as claimed in the claim 19, wherein the data is cyclically timed applied to the operation algorithms for processing.

26. The method as claimed in the claim 19, wherein the multiprocessor system comprises a system selected from the group consisting of:

a multi-core processing unit, a cluster computer, a multi-DSF configuration, a cell processor, a stream processor, and a freely programmable logistics module.

27. The method as claimed in the claim 19, wherein the processing units exchange the data through a common memory unit.

28. The method as claimed in the claim 19, wherein the processing units exchange the data through a common connection network.

29. The method as claimed in the claim 19, wherein the processing units exchange the data via a data packet.

30. The method as claimed in the claim 19, wherein the processing units are connected to each other and statically switched by a connection network.

31. The method as claimed in the claim 19, wherein the processing units are connected to each other and dynamically switched by a connection network.

32. The method as claimed in the claim 19, wherein the allocation of the data is event controlled.

33. The method as claimed in the claim 19, wherein the allocation of the data is scheduledly controlled.

34. The method as claimed in the claim 19, wherein the processing units process the data applied from inputs and output the processed data at outputs for further processing.

35. The method as claimed in the claim 19, wherein the multiprocessor system is used in a medical imaging system.

36. A medical device with a multiprocessor system, comprising:

a plurality of processing units; and

a control unit that;

assigns a plurality of operation algorithms to the processing units respectively for processing a plurality of data allocated to the operation algorithms respectively, and

inserts a plurality of control data to the data respectively for defining the allocation of the data.
