Embodiment Construction
[0042] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0043] The application principle of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0044] An important purpose of intra-kernel communication is to send data from one core to the data processing core for processing. When the data is ready, the sending core usually notifies the receiving core through an inter-core interrupt inside the processor. The interrupt response time of the receiving core is also an important data transmission delay.
[0045] At present, there are already many high-real-time operating systems that can control the interrupt response delay to about...
