4.1 Software Overview
To begin developing applications, you need to install the DVEVM
development environment. This section outlines the steps required to
load the DVEVM software onto the development host. You will need the
three DVEVM distribution CDs 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 DVEVM provides for development on the ARM side. Developers
treat the DSP-side as a black box that is accessible through a set of APIs.
If you want to program the DSP-side directly, the DVSDK (Digital Video
Software Development Kit) supports this capability.
The following software is provided with the DVEVM:
❏
Standalone demonstration software. This is provided on the hard
drive on the DVEVM. The hard-wired examples encode and decode
audio, video, and speech. Another demo shows the board’s network
capabilities. See Section 3.2,
Starting the Standalone Demos .
