Communication interface system of micro-control unit and ARM (advanced RISC (reduced instruction-set computer) machines) processor

Abstract

The invention discloses a communication interface system of a micro-control unit and an ARM processor. The communication interface system comprises a physical layer, a link layer, a transmission layer, an interface layer, a logic layer, an application interface layer and an application layer of the ARM processor, and the micro-control unit, wherein the interface layer is a protocol analyzing interface of the micro-control unit and the ARM processor and used for converting data frames obtained from the transmission layer into interface functions of corresponding service logics; by achieving the interface functions, the service logics can be transmitted to upper layers and converted into data frames for being transmitted to lower layers. Through the technical means of layered service analysis and interface linkage, the communication interface solves the problem of reducing the inter-coupling degree of the service logics and enhancing the intra-coupling degree of the service logics, and further achieves the technical effects of increasing the frame height and the maintainability.

Description

technical field [0001] The invention relates to the field of computer communication, in particular to a communication interface system between a micro control unit and an ARM processor. Background technique [0002] At present, the communication interface system of Android-based processors (such as ARM and MCU) mainly executes processes including protocol analysis, logic processing, jni calling, Android service and application calling, and its structure is complex and diverse. [0003] Such as figure 1 Shown is the existing MCU / ARM communication interface system structure, including MCU layer, physical layer, link layer, logic layer and application layer. In an existing communication system, an application calls an MCU by registering a callback function. The disadvantage of this implementation method is that maintenance is complicated. In the process of waiting for the return value of the function, a thread needs to be opened, and when processing the return value, a UI th...

AI Technical Summary

Problems solved by technology

The processing logic is complex, taking up many threads, and the coupling degree with Android services is too high, and it does not meet the specifications of Android system information processing

[0004] Moreover, the existing communication system architecture has problems such as low fault tolerance performance, high consumption of MCU-related application resources, chaotic logic processing modules in the service layer, difficult maintenance, and complex MCU control logic.
