Processor and method for assigning config id for core included in the same

A method performed by a processing device comprising processing circuitry,

• wherein the processing circuitry comprises a plurality of processors, a memory operably coupled to the plurality of processors, a first data line connecting a plurality of units including the memory and the plurality of processors in series in a forward direction, and a configuration line connecting the plurality of processors in series, wherein each processor of the plurality of processors comprises a configuration register storing a configuration indication,
• the method comprising:
• providing, by the processing circuitry, to the configuration line, a plurality of configuration indication set signals to set configuration indications in configuration registers of the plurality of processors;
• receiving, by a respective one processor of the plurality of processors, a configuration indication set signal;
• setting, by a respective one processor, a configuration indication of the received configuration indication set signal in a configuration register of the respective one processor;
• and
• performing, by a respective one processor, data processing according to the configuration indication set in the configuration register of the respective one processor,
• wherein a data path between the plurality of units is configured on the first data line according to the configuration indications set in configuration registers of the plurality of processors,
• wherein data is transferred via the configured data path on the first data line,
• wherein the configuration indication set in the configuration register of the respective one processor indicates whether the respective one processor is an end unit in the plurality of processors,
• the method further comprising:
• providing a configuration completion signal indicating whether configuration indication setting was successful to a previous unit of the respective one processor when the configuration indication indicates that the respective one processor is the end unit, in response to successfully setting the configuration indication in the configuration register of the respective one processor.
