Classification: CPC G | IPC G

Claim 0:
1. A network-on-chip (NoC) data processing method applied to an NoC processing system, wherein the NoC processing system is used to perform a machine learning operation, and includes a storage device and a computation device, and the method includes:
accessing the storage device in the NoC processing system by using a first computation device in the NoC processing system to obtain first operation data;
performing an operation on the first operation data by using the first computation device to obtain a first operation result; and
sending the first operation result to a second computation device in the NoC processing system,
wherein the computation device includes an operation unit and a controller unit,
wherein the accessing the storage device in the NoC processing system by using the first computation device in the NoC processing system to obtain first operation data includes obtaining, by the controller unit in the first computation device, the first operation data and a computation instruction from the storage device,
wherein the operation unit includes: a tree module which includes a root port and a plurality of branch ports, wherein the root port is connected to the primary processing circuit, and each of the plurality of branch ports is connected to one of the plurality of secondary processing circuits, and
wherein the tree module forwards a data block, a weight, and an operation instruction between the primary processing circuit and the plurality of secondary processing circuits.
