Network-on-chip data processing method and device

A data processing method, comprising:

• receiving a data operation signal sent by an internal or external device, wherein the data operation signal includes an opcode;
• the opcode includes a type flag bit which is used to indicate a broadcast or multicast instruction of the data operation signal;
• and
• performing a corresponding operation according to the data operation signal on data to be operated in a memory to obtain required input data,
• wherein the data operation signal includes an operation field, where the operation field includes a data reception flag bit which is used to indicate a device or a processing circuit that receives the input data,
• wherein a count of data reception flag bits represents a count of devices or processing circuits that can interact with the memory, and
• wherein the operation field further includes information of data to be operated, wherein the information of the data to be operated includes a source address of the data to be operated in the memory, a length of the data to be operated, and a data return address after the data is operated, and the performing a corresponding operation on the data to be operated in the memory according to the data operation signal to obtain the required input data includes:
• reading the memory from the source address to obtain input data that satisfies the data length;
• determining a device or a processing circuit that receives the input data according to the data reception flag bit;
• and
• according to the data return address, returning the input data to a storage space corresponding to the data return address in the device or processing circuit.
