The microkernel can be regarded as an MCU integrated in the multi-core heterogeneous SOC processor, has the highest authority, can be started after being electrified, has an SRAM which is shared independently, can be directly operated without depending on an operating system, and has control and access to DDR and Flash, has independent control serial port configuration, and can monitor the working state of an internal CPU and a GPU and configure the electrifying time sequence in a chip.
In the present embodiment, a large core CPU of a multicore processor is referred to as a first core, and a microkernel MCU is referred to as a second core. The first kernel is used for operating the instrument operating system, and at the moment, the first kernel obtains information such as vehicle speed information, rotating speed information, oil quantity/electric quantity, water temperature and the like from a vehicle body gateway or a vehicle Body Controller (BCM), and provides the information to the display screen 12 to be displayed by the display screen 12. When the host 11 further includes a USB interface or network communication modules such as bluetooth, WIFI, GPRS, etc., the host 11 may also obtain information such as a navigation map and media video, and display it on the display screen 12.
The second kernel always monitors the working state of the instrument operating system operated by the first kernel, and when the instrument operating system is monitored to be abnormal, such as breakdown, starting and the like, the second kernel starts to acquire the vehicle body information of a vehicle body gateway or a vehicle body controller BCM and provides the vehicle body information to the display screen for displaying, so that the normal display of the vehicle body information is still ensured when the instrument operating system is abnormal, and the driving safety is fully ensured.
Further, if the second kernel monitors that the meter operating system is restarted and then returns to a normal working state, the second kernel returns the display permission of the whole vehicle meter information display device to the first kernel, and the meter operating system operated by the first kernel continuously displays information such as vehicle speed information, rotating speed information, oil quantity/electric quantity, water temperature, navigation map and media video through the display screen.
