Assignee: GUANGZHOU UNIVERSITY
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. 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.
