Abstract

The invention discloses an information model modeling and generating method of a microprocessor. The method is based on a CIM modeling theory and method. Various constituent unit information entitiesof tan MCU are abstracted; CIM models of MCU cores, core peripherals and various interfaces of different instruction set frameworks are established. Based on an established MCU CIM model, for a specific model MCU, a corresponding CIM instance model is established. According to the invention, the universality and the expandability are good; the method can be used for carrying out abstract description, unified modeling and formal verification on MCU information of various different instruction set architectures and interface types, the generation method allows a user to automatically generate part of assembly language files or C language header files in underlying software according to the established information model, and the underlying software development efficiency and quality are improved.

Description

Technical field [0001] The invention relates to an information model description and generation method of an embedded system hardware circuit, and specifically aims at the information modeling and generation method of various constituent units of a microprocessor. Background technique [0002] At present, various open source microprocessors (Micro Controller Unit, MCU) are becoming more and more popular, and their architecture has the advantages of latecomer technology and good application prospects. Since its birth, it has been widely used in various embedded products more and more. However, the problems brought by open source have also appeared. The user-defined and tailorable characteristics of the MCU have brought the MCU presents the characteristics of diversified structure, customized interface and integrated application, which is to make full use of the hardware resources of the MCU and its interfaces. , Reasonably construct safe and effective application products, softwa...
