A service bus microkernel framework design method based on formal specifications

The invention discloses a formal specification-based service bus microkernel framework design method, which comprises the following steps of: firstly, carrying out formal description on natural language specifications, and abstracting formal specifications of communication primitives among processes by utilizing Hall logic; then developing a design framework based on formalized description; defining an event service bus in the micro-kernel framework, directly receiving an event that falls into the kernel through the inter-process communication primitive by the event service bus, and determining whether to switch to a network service agent or a local service for processing according to the acquired data; enabling The event service bus to search the corresponding system service according tothe service number and call the system service to complete corresponding functions; enabling the system service to directly interact with the hardware, and return a result; processing Hardware interruption generated by the co
