Algorithm 5

NoC_WS_REGULAR_HXN.
Input: n, stores Number of parallel processing NoC.
Source, a NoC type array, stores the Source NoC Numbers a part of NoC structure.
Destination, a NoC type array, stores the Destination NoC Numbers a part of NoC structure.
Payload, a part of NoC structure that holds the data generated as Source NoC.
Output: Payload.
