Software Overview

4.1Software Overview

To begin developing applications, you need to install the DVEVM development environment. This chapter outlines the steps required to load the DVEVM software onto the development host. You will need the distribution disks or the files they contain to get started.

The DaVinci software approach provides interoperable, optimized, production-ready video and audio codecs that leverage DSP and integrated accelerators. These codecs are built into configurable frameworks, and are presented via published APIs within popular operating systems (such as Linux) for rapid software implementation.

The following software is provided with the DVEVM.

❏Standalone demonstration software. This is provided on the hard drive on the EVM. The hard-wired examples encode and decode audio, video, and speech. Another demo shows the board’s network capabilities. See Section 3.2 and Section 3.5.

❏Disk 1: MontaVista Linux Pro v5.0 System Tools and Target File System. The version provided with the DVEVM kit is the demonstration version. It contains the following file:

■mvl_5_0_demo_sys_setuplinux.bin. This installation file contains the MontaVista Tool development tool chain and the target file system.

❏Disk 2: TI DVSDK Software. This DVD includes demo applications, Codec Engine software, example codec servers, and DVEVM documentation. It contains the following files:

■this manual in PDF format

■dvsdk_setuplinux_#_#_#_#.bin (DVSDK installer)

■mvl_5_0_0_demo_lsp_setuplinux_#_#_#_#.bin

■xdctools_setuplinux_#_#_#.bin (XDCtools installer)

■bios_setuplinux_#_#_#.bin (DSP/BIOS installer)

■TI-C6x-CGT-v#.#.#.#.bin (TI Code Generation Tools installer)

■SoCAnalyzer_#.#.#.#.exe. SoC Analyzer installer.

■data.tar.gz (Contains A/V data files for use by the demos)

■restore/overlay.tar.gz (Contains demo files in case they are needed for recovery. You can generally ignore this file.)

❏Disk 3: SDI Board Support Software. This disk contains ARM- based test code, CCStudio GEL files, and other EVM support software.
