This application discloses a processor, a processing method, and a related device. The processor includes a processor core. The processor core includes an instruction dispatching unit and a graph flow unit and at least one general-purpose operation unit that are connected to the instruction dispatching unit. The instruction dispatching unit is configured to: allocate a general-purpose calculation instruction in a decoded to-be-executed instruction to the at least one general-purpose calculation unit, and allocate a graph calculation control instruction in the decoded to-be-executed instruction to the graph calculation unit, where the general-purpose calculation instruction is used to instruct to execute a general-purpose calculation task, and the graph calculation control instruction is used to instruct to execute a graph calculation task. The at least one general-purpose operation unit is configured to execute the general-purpose calculation instruction. The graph flow unit is configured to execute the graph calculation control instruction.
