Short message equipment universal communication interface based on fully domestic CPU and OS

Abstract

The invention discloses a short message equipment universal communication interface based on a fully domestic CPU and an OS, and belongs to the field of communication interfaces. The communication interface is provided with a common functional interface aimed at short message equipment in an extracting and packaging mode according to an AT instruction and common functions of the short message equipment, an interface used for being called by a JAVA program is achieved by adopting the JNI technology, a serial port communication function library is achieved by adopting a standard POSIXAPI, separation between equipment communication and upper-layer calling is achieved by using a layering design, and an inheritance-hierarchy-like relation is designed by using the polymorphism of the C++. Compared with the prior art, the short message equipment universal communication interface based on the fully domestic CPU and the OS has good universality and expandability and has good popularization and application value.

Description

technical field [0001] The invention relates to the field of communication interfaces, in particular to a general communication interface for short message equipment based on a nationally produced CPU and OS. Background technique [0002] In the context of information security, all kinds of information security has become a crucial issue. In recent years, the Chinese government has invested a lot of financial and material resources in the development of information technology software and hardware products with independent intellectual property rights to improve core competitiveness and ensure my country's information security. [0003] Nuclear high base is the abbreviation of "core electronic devices, high-end general-purpose chips and basic software products". High-end general-purpose chips mainly refer to the central processing unit of electronic computers, which are the most difficult to develop in the computer industry. At present, the domestic CPUs mainly include the...

Problems solved by technology

[0006] However, due to the difference between the instruction set of the domestic CPU and the mainstream intel and AMD products in the market, the communication interface package and software products of the SMS equipment manufacturer cannot be run and used on the whole machine based on the domestic CPU.
