Description

Graphic processing method based on the C language micro operation system

Technical field

The present invention relates to a kind of graphic processing method based on uCos-II (MicroC-OS-II is based on the micro operation system of C language) operating system.

Background technology

The research of graphic user interface is the key areas of embedded system research.Along with the development of embedded device and the raising of software and hardware condition, embedded system is also more and more urgent to the demand of high-performance, highly reliable graphics system.Because most embedded device is all more limited on processing power and storage space, compare with the graphical user system on the General System, the requirement of the graphic system under the embedded system is higher, need possess light-duty, take that resource is few, high-performance, high reliability, characteristics such as configurable.

Summary of the invention

A kind of graphic processing method provided by the invention based on the C language micro operation system, the Modern Graphic windowing environment is incorporated on the small-sized platform of operation uCos-II operating system, the extensibility and the portability of system have been improved, realize user's operations such as demonstration, selection, modification at interface at screen by bottom layer driving, finish the mutual of set-top box server and user-to-user information.

In order to achieve the above object, the invention provides a kind of graphic processing method based on uCos-II operating system, it comprises request process and incident acquisition process;

Described user end to server end sends request process and comprises following steps:

The request of step 1.1, client sends;

The various mapping operations of step 1.1.1, client all can use the AllocReq function to produce corresponding request, are pressed into request queue, require server end to finish corresponding concrete operations;

After step 1.1.2, request queue have by the time all been filled up, all requests in the request queue are passed to server end, request is waited in refresh requests formation then again;

The request of step 1.2, server end receives;

The GsSelect function of step 1.2.1, server end is responsible for receiving the request that client sends, call event response according to request type and handle function G sHandleClient, be used to resolve the request with distribution customer terminal, obtain the entry address of corresponding built-in function, call this built-in function;

After a series of built-in functions that step 1.2.2, server end call were finished different requests, if there are data to return, then function can directly return to client to result data;

Described client obtains incident and comprises following steps to the process that server end sends event request (comprising event types such as keyboard, mouse, graphic presentation):

Step 2.1, since graphic system in operational process, constantly adopt the mode of interrupting to obtain event information, the incident (comprising that keyboard, mouse, Exposure are event types such as graphic presentation) that client at first uses GrSelectEvent to select client to respond;

Step 2.2, client call interface function GrGetNextEvent obtain external remote, the incident of man-machine input such as keyboard;

Step 2.3, call the data that the GrRequestClientData function generates concrete event request, send request to server end; Call the GrSendClientData function event request is pressed into the formation of transmission request msg;

Step 2.4, hang-up client are blocked outside input, wait pending data;

Step 2.5, user will write variety of event to the response demand of incident according to oneself and handle function, call this function afterwards, finish user's mapping operation.

The request that client sends in the above-mentioned steps 1.1 is finished by a series of built-in functions, comprises as follows:
