abstract： in video decoding， almost all the davinci decoding platform is used of linux operation system. this paper designed a video decoding platform， and based on this platform the h.264 video stream has been decoded. it shows that the program has gotten better results.关键词： tms302dm6467；h.264；图像解码key words： tms302dm6467；h.264；video decoding中图分类号：tp311.5 文献标识码：a 文章编号：1006-4311（2013）24-0177-030 引言h.264视频标准由于其显著的压缩比，良好的网络亲和性，较强的抗误码特性等，其应用前景将覆盖整个视频应用领域。

目前针对h.264标准的视频编解码硬件平台一般通过达芬奇（davinci）芯片实现。

软件开发都是在linux操作系统下完成。

作为平台硬件与操作系统内核之间的接口，设备驱动程序在操作系统下为应用程序屏蔽了硬件细节，硬件设备对应用程序只有一个设备文件，其对硬件设备的操作同普通文件操作一样。

在一些特殊应用场合，用户需要对硬件平台的底层运行行为充分掌握，并对软件流程与代码进行充分评测，这就需要达芬奇硬件平台在无操作系统支持下完成针对h.264高清视频流的解码工作。

You may skip sections if you do not need to access a particular peripheral. For example, if you do not need to use the serial cable, skip that section.1)The EVM is sensitive to static discharges. Usea grounding strap or other device to prevent damaging the board.Be sure to connect communication cables before applying power to any equipment.2)Verify that the EVM board’s EMU0/1 select switch (S1) is setcorrectly. The settings shown here enable both ARM and DSP JTAGfor emulation debugging.Setting Up the HardwareEVM Hardware Setup 2-33)Verify that the EVM board’s SW3 boot/muxing configuration switch iscorrectly set. The BM1, BM2, and BM3 switches should be set to On.These switch settings, which are shown in the following figure,enable the following:■SPI boot mode■EMIF A is 8-bit data bus for CS2■PCI pin multiplexing enabled on DM6467■DSP is booted via ARM processor4)Connect the Ethernet cable to the Ethernet port on the EVM boardand to an Ethernet network port. Note that the U-Boot bootargs mustinclude "ip=dhcp" to enable the network connection.Setting Up the Hardware2-45)Connect a video source (for example, a camera or DVD player) to thecomponent input video connectors (J1, J2, J3). Note: To run the demos described in Chapter 3, you will need to have an HD (720p) video source connected to the EVM board's component input connectors.6)Connect your video display to the EVM board’s component outputvideo connectors (J10, J11 and J12) using the component cables included with the DVEVM kit. Note: To run the demos described in Chapter 3, you will need to have an HD display connected to the EVMboard's component output connectors.Setting Up the HardwareEVM Hardware Setup 2-57)Connect an audio speaker to the headphone connector (P4).8)Connect an audio source to the microphone connector (P8).Setting Up the Hardware2-69)If you plan to use the UART port for a console window, connect theRS-232 null modem cable to the EVM UART port (P1) and to the COM port of your host workstation.10)Power on your video input and output devices.11)Connect the power cable to the EVM power jack on the board. To beESD safe, plug in the other end of the power cable only after you have connected the power cord to the board. Then turn on the board.12)The initial screen of the demo software should be displayed on yourvideo output device. Use the IR remote to run the software asdescribed in Chapter 3.Connecting to a Console Window 2.2Connecting to a Console WindowYou can open a console window that allows you to watch and interruptEVM boot messages by following these steps:1)Connect a serial cable between the serial port on the EVM and theserial port (for example, COM1) on a PC.2)Run a terminal session (such as Minicom on Linux or HyperTerminalon Windows) on the workstation and configure it to connect to thatserial port with the following characteristics:■Bits per Second: 115200■Data Bits: 8■Parity: None■Stop Bits: 1■Flow Control: None3)When you power on the EVM, you will see boot sequence messages.You can press a key to interrupt the boot sequence and typecommands in the U-Boot command shell.

It does not require an NFS mount or a TFTP server to run the standard demos. Note: The default U-Boot bootargs definition sets "ip=off", which disables the Ethernet connection.The out-of-the-box boot parameters are listed in Section A.3.1. The following are alternate ways you may want to boot the board:❏TFTP boot with hard drive file system (Section A.3.2)❏Flash boot with NFS file system (Section A.3.3)❏TFTP boot with NFS file system (Section A.3.4)To abort the standard boot, press any key in the console window (see Section 2.2). Also see Section A.3, Alternate Boot Methods if you want to change the boot configuration.3.2Starting the Standalone DemosWhen you connect the EVM hardware, the pre-loaded examples run automatically on the display connected to the EVM board's component output connectors, using a 720p (HD) video source connected to the component input connectors. These examples encode and decode audio, video, and speech. There are two ways to use the demos:❏Standalone. This is the default power-on mode. The demos run automatically with no connection to a workstation in the default bootconfiguration. This is the mode documented in the rest of this chapter.The standalone demo was set up by the DVSDK, which copies the file /examples/dvevmdemo to the directory /etc/rc.d/init.d (the central repository for startup scripts). This file is symbolically linked to /etc/rc.d/rc3id/S88demo. When the board boots up and enters runlevel 3, this file is executed to start the demo web server and the demo interface.❏Command line. Once you have connected the EVM to a workstation and installed the necessary software (as described in Section 4.3.1,Installing the Target Linux Software ), you can run the demos from the board’s Linux command line. For further information on running the demos from the command line, see the demo documentation that is linked to by the DVSDK release notes.Note: When you run the demos from the command line, make sure the interface process used by the standalone mode demos is notStarting the Standalone DemosRunning the Demonstration Software 3-3running. Otherwise you will see error messages raised when device drivers fail to open.Once the EVM board has booted, the displayshould show a picture of the remote control.You use the IR remote to control the demos.The order of the buttons on the actual remotemay be different from the picture; if yourremote looks different, find the buttons withthe same labels on your remote.To use the demos in standalone mode, followthese steps:1)Check to make sure the batteries areinstalled in your IR remote.2)Make sure an HD (720p) video source isconnected to the EVM board'scomponent input connectors. Also makesure an HD display is connected to theEVM board's component outputconnectors.Note: The demos do not currentlysupport composite video output.3)The initial screen shows a diagram of theIR remote, which you use to run thestandalone demos. Take a minute to lookat the functions of the various buttons.4)Since this is a universal remote, you mayneed to set it to use the codes necessaryto run the DVEVM demos. To do this, holddown the "Code Search" button until thered light on the remote stays lit. Thenpress the "DVD" button and enter "0020"as the code.5)If you accidentally put the remote in TV or some other mode, press"DVD" to return the remote to the correct mode.6)If the remote does not accept the DVD+0020 code, do a full reset byremoving the batteries, pressing the Power button for at least a minute, then reinserting the batteries. Then program the remote as in Step 3.。
