概要

The Linux Digital Video Software Development Kit (DVSDK) for DaVinci™ processors provides everything developers need to evaluate and start developing on the DM37x Cortex™-A8 DSP+ARM® microprocessors. With the included Graphical User Interface (GUI)-based Matrix Application Launcher, launching demos, benchmarks, and applications is a snap. Furthermore, developers will find it easy to develop applications and add them to the Matrix Application Launcher. The DVSDK also includes DSP-accelerated audio and video codecs, as well as tools to easily leverage the DSP for other signal processing tasks.

This is the Generally Available (GA) release of the Linux DVSDK version 4.x. Supported platforms are TMS320DM365, OMAP-L138, and TMS320DM3730/25 processors.
 

Additional Information:

特長

The Linux SDK for DM3730 and DM3725 includes the following components:

  • Linux kernel 2.6.37
  • Bootloaders
  • File System
  • Qt/Webkit application framework
  • Matrix Application Launcher
  • 3D Graphics support
  • WLAN & Bluetooth support
  • Example applications
  • Host tools including Flash Tool and Pin Mux Utility
  • Documentation
  • Tools for easy development/integration of DSP algorithms
  • DSP accelerated codecs: JPEG Encode/Decode, MPEG4 SP Encode/Decode (up to 720P), H.264 BP Encode/Decode (up to 720P), MPEG2 MP Decode (Dup to 720P), G.711 Encode/Decode, AAC LC/HE Decode, MP3 Decode

 

The DM37x Linux DVSDK is free, and does not require any run-time royalties.


 

What is in DVSDK v4?

  • Bootloading (u-boot) - Software to boot Linux from a variety of peripherals.
  • The Codec Engine Multimedia stack - The Codec Engine algorithm execution framework provides a consistent set of multimedia codec APIs, known as xDM, regardless of whether the codec is being executed on the ARM, DSP, or dedicated accelerator. Developers can then build higher-level multimedia framework functions, such as AV Sync or stream parsing, on top of Codec Engine. For developers whose expertise is in Linux application development, Codec Engine enables developers to remotely instantiate and execute codecs and algorithms on the DSP without needing to write any DSP code.
  • DaVinci Multimedia Interface (DMAI) - DMAI allows development of highly portable multimedia applications that can move easily from one device or operating system to another.
  • Multimedia codecs - The DVSDK provides codec libraries and associated AV clips that enable developers to immediately develop and evaluate real-world applications. These codecs may be in dedicated hardware (DM355S), DSP-accelerated or a combination of both. Most are available for download now, along with the DVSDK. They are production quality codecs, with production software licensing agreements.
  • Demonstration ("Demo") programs - The Demo programs show decoding and encoding operations to illustrate how frameworks, codecs, video and audio subsystem drivers are integrated to implement complete applications.

 

For DaVinci and Integra devices that have DSP cores, the DVSDK further offers a set of DSP components that allow developers to quickly leverage DSP acceleration, including:

  • DSP/BIOS operating system - DSP/BIOS is a preemptive, multitasking, real-time kernel that simplifies creation of multithreaded DSP application.
  • DSP/BIOS Link - DSP/BIOS Link is ARM-DSP communication software that enables the ARM to bootload the DSP and for the two processors to pass messages and data buffers via shared memory.
  • xDAIS Developer’s Kit - xDAIS and xDM are algorithm integration standards that make it easier to implement applications that must use multiple different codecs. Algorithms adhering to the xDAIS standard access shared resources such as internal memory and DMA through the framework, enabling the framework to prevent one codec overwriting the resources used by another. xDM provides standard APIs for different classes of codecs that enable an application to invoke, for example, MPEG4 or H.264 decoders from different vendors without having to change any code.
  • Framework Components - Framework Components are modules that simplify implementation of frameworks that wish to use xDAIS-compliant algorithms.
  • EDMA3 Driver - This driver provides APIs to utilize DaVinci’s powerful DMA capabilities. The EDMA3 driver includes resource management support to enable developers to safely share DMA resources between different parts of the application.
  • Development Tools - Although Codec Engine enables applications to use DSP-accelerated codecs without doing any DSP programming, developers who need to implement custom DSP applications will need to purchase TI's Code Composer StudioTM IDE and an emulator. These will allow development and debugging of applications on the DSP.
