In response to the characteristic of traditional game devices mostly using microprocessors and microcontrollers, which are not easily upgraded, this paper transplants the Cortex-M0 soft core onto an Field Programmable Gate Array (FPGA). Through the collaborative work of software and hardware, an intelligent aircraft combat game machine based on the FPGA is constructed. The experimental results show that the game has good human-machine interaction. It also demonstrates the high flexibility of building the Cortex-M0 soft core on FPGA for collaborative work, allowing for easy hardware expansion and upgrades on the existing hardware resources.
