  • Patent number: 12001832
    Abstract: There is provided a control chip including a microcontroller unit (MCU), a bus arbiter, a first bus, a second bus, a void hardware, a cache controller, a flash controller and a flash memory, wherein the flash memory is recorded with a firmware. When the MCU does not receive an update instruction, the bus arbiter reads, according to a function command of the MCU, a function return value associated with the function command from the flash memory via the first bus, the cache controller and the flash controller. When the MCU receives the update instruction, the bus arbiter updates the firmware in the flash memory via the second bus and the flash controller, and the void hardware actively replies a void return value associated with the function command to the MCU to replace the function return value.
