Description: Serial Advanced Technology Attachment (SATA) is a serial link replacement of
Parallel ATA (PATA), both standards for communication with mass storage devices.
This high-speed serial link is a differential layer that utilizes Gigabit technology
and 8b/10b encoding. Some of the features of SATA compared to PATA
are increased transfer speed, hot-plug capability, and Native Command Queuing
(NCQ). The link supports full duplex but the protocol only permits frames in one
direction at a time. The other non-data direction is used for flow control of the
data stream.
Figure 2.1. The layers of the SATA protocol
SATA’s architecture consists of four layers (see Figure 2.1), Application, Transport,
Link, and Physical. The Application layer is responsible for overall ATA commands

Description: Linux的网络协议栈是内核的一部分，它的实现是基于TCP/IP协议栈的，共分五层，分别是：应用层、BSD Socket层、INET Socket层、网络层和数据链接/硬件层。这是继承了unix的网络系统，现在linux的网络系统不断注入了新的理论。
我要研究的是linux下网络协议栈一个通信协议——TCP协议栈。TCP协议是面向对象的协议，本论文主要从缓存sk_buff，TCP相关数据结构，TCP连接的建立与关闭，TCP数据的发送与接收，TCP的流量控制与拥塞控制这几方面阐述我对TCP协议栈的理解，主要研究了TCP在内核中如何实现，以及一些算法的实现。
-Linux network protocol stack is a core part of its implementation is based on TCP/IP protocol stack is divided into five, namely: the application layer, BSD Socket Layer, INET Socket layer, network layer and data link/hardware layer. This is the inheritance of the unix network system, network system is linux and keep adding a new theory. I need to study is a network protocol stack under linux communication protocols- TCP protocol stack. TCP protocol is object-oriented protocol, this thesis from the cache sk_buff, TCP data structures, TCP connection establishment and closure, TCP send and receive data, TCP flow control and congestion control these areas and explain my TCP protocol understanding of the stack, a major study how TCP in the kernel, and some algorithm.

Description: 串口通讯实验：
本实验得到的结果为，打开超级终端，设置波特率为115200，数据流控制位为无。运行系统，就会显示“UART & Interrupt Experiment,Please Input from the keyboard”，我们就可以通过写串口操作。
在flash调试时，需要修改RO BASE为0x00000000，其他不用修改，重新编译下载就可运行。
注意：由于系统产生中断，程序计数器就会跳到0x18处执行中断服务子程序，所以不能在SDRAM调试。 -Serial communication experiment: the results of this experiment, open HyperTerminal, set the baud rate to 115200, data flow control bit is not. Operating system, it will display " UART & Interrupt Experiment, Please Input from the keyboard" , we can write the serial port operation. Debug in flash, you need to modify the RO BASE is 0x00000000, the other not modify, recompile download can run. Note: Due to system interrupt, the program counter will jump to 0x18 Department execute the interrupt service routine, it can not debug the SDRAM. Platform: |

Description: This example shows a simple communication stream between a client and a server over TCP/IP. The server program also demonstrates a simple multi-threaded connection monitoring routine.
The example programs do not attempt to implement a data transmission protocol. All messages are read in 64 byte chunks and the server does not attempt to relate multi-part messages from clients. However, comments in the code indicate the places where changes would be made to accomodate multi-part messages and/or alternate message frame size schemes.
A client/server application is a two-part problem: first you must define the raw data transmission methodology for the programs, and second you must then implement a data transmission protocol to control the flow of the raw data and make it meaningful to the applications. This sample only attempts to deal with the first part of the problem transmitting the raw data.-This example shows a simple communication stream between a client and a server over TCP/IP.
