| Abstract | In order to meet the actual needs of operating system localization and high-security operating system, this paper proposes a multi-core embedded high-security operating system inter-core communication mechanism centered on private memory on the core based on the cache mechanism of DSP processors such as Feiteng design. In order to apply it to the multi-core embedded high-security operating system, this paper also combines the priority scheduling scheme used in the design of our actual operating system to analyze the certainty of inter-core communication. The analysis result is: under this communication mechanism There is an upper limit for end-to-end delay, so the certainty of the communication mechanism is guaranteed and can be applied to multi-core high-security embedded operating systems. |
