Path creation method and device for network on chip and electronic apparatus

A path creation device for a network on chip, comprising:

• a receiving unit configured to receive a first data packet sent by a first network node, wherein the first data packet carries first idle address identification information, a destination network node address and path creation identification information, the first idle address identification information indicates a first idle position in a first path routing table of the first network node, the path creation identification information indicates a creation of a path;
• a storing unit configured to store the first idle address identification information in a second idle position in its second path routing table, and determine second idle address identification information, wherein the second idle address identification information is address information of the second idle position in the second path routing table;
• a determining unit configured to determine a second data packet according to the second idle address identification information;
• and
• a sending unit configured to send the second data packet.
