Message-based processing system and method of operating the same

A method of operating a message-based processor system, comprising a first plurality of message-based processor system cores, the method comprising:

• providing a second plurality of storage locations for maintaining respective processor element states, each of the second plurality of storage locations having a respective processor element address;
• providing respective pluralities of third addressable storage entries and storing therein pattern information of respective target patterns, the pattern information comprising, for respective pattern elements of a respective target pattern, both a magnitude indicator with a magnitude value and a control indicator with a control value;
• receiving as an input message an event message comprising a target pattern indication with a target pattern indication value and a target processor element subset indication with a target processor element subset indication value;
• selecting an initial address computation mode from a cyclic set of address computation modes;
• determining a processor element address in accordance with the target processor element subset indication value;
• designating one of the third addressable storage entries of a pattern element in accordance with the target pattern indication;
• retrieving, from the designated one of the third addressable storage entries, the magnitude value and the control value;
• updating a state of the processor element specified by the processor element address in accordance with the magnitude value;
• selectively selecting, in accordance with the control value, a next address computation mode in the cyclic set of address computation modes;
• computing a subsequent processor element address in accordance with a current address computation mode as determined by the selectively selecting the next address computation mode;
• determining a subsequent third addressable storage entry;
• and
• repeating the retrieving from the third addressable storage entry and succeeding updating, selectively selecting, computing and determining operations until a stop condition is valid.
