Problems solved by technology

[0011] However, the existing methods still have great defects in adaptability and scalability
The layering of the supporting functions of the entire device is too rough, and only the "device-independent operating system input and output software" can achieve a unified interface. Therefore, a large number of repeated codes are required for special processing for each specific device. Adaptability and scalability, so hot plugging is not well supported

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] The present invention is laid out according to the above-mentioned four-layer management system and two auxiliary modules. The system will be introduced in detail below.

[0028] 1) Divided into four layers of management system and two auxiliary modules, see attached figure 2 :

[0029] ① Divided into four layers of management system:

[0030] I. Device interface: abstract the hardware device, encapsulate the hardware device, have a unique identifier and provide an interface for operating the hardware device. Object-oriented method is adopted in the present invention, and equipment interface is the object in Java operating system, and each equipment interface all is instantiated into an object according to corresponding equipment, abstracts the function of specific hardware equipment, and externally shows as a standard equipment , and variou...

Abstract

The invention discloses a realization method of equipment support in the Java operation system, which is characterized by the following: adapting stratified management pattern to use facing object method in the Java operation system; dividing the equipment support system into four layers: equipment interface, equipment bus interface, equipment driving program and equipment applying program interface; making each object realize by each layer in the operation system; finishing self-identification and register through the assisting self-searcher of equipment searcher and driving mapper connecting the equipment on the equipment bus. The invention displays high adaptability and expandability, which can support equipment hot-connet better.

Description

technical field [0001] The invention relates to a Java operating system, in particular to a method for implementing device support in the Java operating system. Background technique [0002] Device support is the most cumbersome and complex part of the entire operating system. Different types of devices from different manufacturers and different models need to be treated separately, and new devices emerge in an endless stream, making it extremely difficult to design a device support method that is widely applicable to various devices. [0003] In order to facilitate the design, the current operating system often divides the equipment into several categories, and deals with each category separately. [0004] According to the input and output characteristics, devices can be divided into three types: input peripherals, output peripherals and storage peripherals. According to the unit of input and output information exchange, it can be divided into character devices and block ...
