A complex computing device, a complex computing method, an artificial intelligence chip and an electronic apparatus are provided. An input interface receives complex computing instructions and arbitrates each complex computing instruction to a corresponding computing component respectively, according to the computing types in the respective complex computing instructions Each computing component is connected to the input interface, acquires a source operand from a complex computing instruction to perform complex computing, and generates a computing result instruction to feed back to an output interface. The output interface arbitrates the computing result in each computing result instruction to the corresponding instruction source respectively, according to the instruction source identifier in each computing result instruction.
