Description: osapi 2.0 操作系统抽象层
\"系统抽象层\"使得你可以实现一种对于RTOS、CPU和所运行产品物理特性完全透明的软件。使用这种公共通用接口，高层软件在并不了解底层硬件特性的情况下也可以访问底层服务，比如对非易失性内存的读写。 -osapi 2.0 Operating System Abstraction Layer "system abstraction layer" allows you to achieve an RTO S, CPU and the operating characteristics of the physical products fully transparent software. Public use of such common interface, high-level software is not in understanding the underlying hardware characteristics of the bottom can also access services, For instance, nonvolatile memory read and write.

Description: 介绍了在嵌入式Linux操作系统下嵌入式GUI的图形抽象层GAL的地位及其设计思路,研究了GUI的设计逻辑,着重阐述了如何在中低端设备上利用FrameBuffer来为上一层提供更加通用的图形接口。主要在色彩转换、利用FrameBuffer进行矩形绘制、内存映像空间的操作以及窗口Z序等方面做了深入的探讨。目前,己经将图形图像部分的研究成果成功运用于福建海媚科技的嵌入式KTV系统中,并积极地向其它嵌入式系统中进行移植。-Introduced in the embedded Linux operating system embedded GUI graphics abstraction layer GAL Platform: |

Description: *** ***OC_I2C_Master使用说明*** *****
使用步骤：1.将OC_I2C_Master文件夹拷贝到安装盘\altera\kits\nios2\components目录下。
之后重新打开SOPC Builder，在可用元件列表的DeviceSOPC组中将出现OC_I2C_Master
元件，即可像其它Altera外设元件一样添加和使用。
2.hdl文件夹中包含有描述i2c逻辑的硬件描述文件，不能删除。
3.HAL文件夹包含硬件抽象层所需的文件（即驱动），不能删除。
4.inc文件夹包含有定义底层硬件的C语言头文件，不能删除.
5.I2C_doc文件夹下有关于该元件的开发文档。-********* OC_I2C_Master use*********** use these steps: 1. OC_I2C_Master folder will be copied to the installation disk alterakits ios2components directory. Re-open after the SOPC Builder, a list of available devices will appear DeviceSOPC Group OC_I2C_Master components, can be similar to other peripheral devices like Altera add and use. 2.hdl folder contains logical description i2c hardware description files, can not be deleted. 3.HAL folder contains the necessary hardware abstraction layer file (ie drivers), can not be deleted. 4.inc folder contains the definition of the underlying hardware C language header files, should not delete. 5.I2C_doc folder on the development of document components.
