A method for generating an accelerator program is disclosed, to help increase utilization of an accelerator and increase program development efficiency. In some feasible implementations of the present invention, the method includes: obtaining an accelerator program description that is based on a state machine, where the accelerator program description includes multiple state machines separately configured to implement an application program, and the multiple state machines form a pipeline according to a data dependency in a directed acyclic graph DAG corresponding to the application program; and performing state machine splicing on the state machines in the accelerator program description by using an accelerator compilation tool, to generate an accelerator program.
