Embodiment 1

[0046] An embedded system software and hardware decoupling architecture based on models and middleware proposed by the present invention includes communication and hardware and OS decoupling modules, general mathematical calculation and hardware decoupling modules, function code scheduling and OS decoupling modules, and Storage read-write and hardware decoupling module. The architecture steps are as follows:

[0047] S1. Completely abandon the structured programming idea of ​​combining and expanding "files, functions, variables" to form code, introduce the concept of object-oriented "model", abstract and design various models, and model (an object, corresponding to a certain real world Things) and their interconnection constitute software code, laying a solid foundation for the complete decoupling of software and hardware;

[0048] S2. Supported by model abstraction, build four middlewares including communication, computing, operating system interface, storage read and write,...

Abstract

The invention relates to the field of system software and hardware decoupling architectures, in particular to an embedded system software and hardware decoupling architecture based on a model and middleware. The system comprises a communication and hardware and OS decoupling module, a general mathematical calculation and hardware decoupling module, a function code scheduling and OS decoupling module and a storage read-write and hardware decoupling module. According to the method, in the field of embedded software design, a structured programming thought that codes are formed by combining and expanding files, functions and variables is thoroughly abandoned, an object-oriented model concept is introduced, various models are abstracted and designed, and a solid foundation is laid for software and hardware decoupling. And the function realization is decoupled from the control, IO and communication, and codes of the functions are not mixed in the function realization. And efficient multiplexing in a model form can be realized. A complex communication form (on-chip / inter-chip, multiple communication links and multiple communication protocols) of an embedded system serves an application layer by a uniform interface, and is decoupled from hardware and an OS (Operating System).

Description

technical field [0001] The present invention relates to the field of system hardware and software decoupling architecture, in particular to a model and middleware-based embedded system software and hardware decoupling architecture. Background technique [0002] The main characteristics of the embedded processing system are as follows: There are various types of processing chips and the structure is quite different from that of the computer CPU, and has its own unique instruction set. Common processing chips include: DSP (TIC6x series), PowerPC, FPGA, FT6678 (domestic DSP), ARM, Phytium series (domestic CPU, ARM core), Huawei HiSilicon, etc. There are many types of operating systems and they are related to chips. The common ones are SYSBIOS (DSP), OSE (DSP, PowerPC), VxWorks (PowerPC), Ruihua (DSP, domestic), Tianmai (PowerPC, Phytium, etc., domestic). The operating system has high real-time performance, which is mainly reflected in interrupt response and inter-thread commu...
