Abstract

Disclosed is a processor element including a plurality of power supply interfaces, a plurality of power supply switches, and a fault-testing unit for testing whether a short-circuit to a connected adjacent processor element has occurred at a power supply interface. The respective power supply switch is closed in case no short-circuit has occurred such that electricity can be fed to the respective power supply interface.

Claims

a multiplicity of processor elements, each processor element comprising;

at least one processor;

a plurality of power supply interfaces for transmitting electricity from and to a plurality of processor elements adjacent to the respective processor element;

a plurality of power supply switches, each power supply interface being assigned a power supply switch, with which electricity can be supplied or not supplied to the respective power supply interface as desired;

testing means for sequentially testing whether there is an electrical short-circuit at a power supply interface to a coupled adjacent processor element;

control means for closing the respective power supply switch so that electricity can be supplied to the power supply interface when there is no short-circuit on the power supply interface; and

wherein at least to some extent, only the processor elements that are arranged locally directly adjacent to one another are coupled to one another in order to exchange electronic messages and to transmit electricity.

2. The processor array of claim 1, wherein at least some of the processor elements have a sensor or an actuator that is coupled to the processor, and wherein sensor data or actuator data is transmitted in the electronic messages between the processor elements arranged adjacent to one another.

6. The processor array of claim 1, wherein the processor elements are arranged in matrix form in rows and columns.

7. The processor array of claim 1, further comprising at least one interface processor that provides a message interface of the processor array.

8. The processor array of claim 2, wherein sensor data or actuator data is transmitted in the electronic messages from and to the interface processor.

9. A fabric structure comprising:

a processor array having a multiplicity of processor elements, each processor element comprising;

at least one processor;

a plurality of power supply interfaces for transmitting electricity from and to a plurality of processor elements adjacent to the respective processor element;

a plurality of power supply switches, each power supply interface being assigned a power supply switch, with which electricity can be supplied or not supplied to the respective power supply interface as desired;

testing means for sequentially testing whether there is an electrical short-circuit at a power supply interface to a coupled adjacent processor element;

control means for closing the respective power supply switch so that electricity can be supplied to the power supply interface when there is no short-circuit on the power supply interface; and
