Digital video technology will undoubtedly reshape the entire electronics industry. Of course, digital video technology is also making profound changes to our video experience, transmission and interaction. It has begun to enter our cars, computers, mobile phones and the Internet. However, bringing high-quality entertainment is just the beginning of the excitement!
In the past, engineers had very limited choices when implementing digital video. Hardwired and ASIC-based solutions always limit the future and functionality of the device and limit their adaptability. While dedicated devices are slightly more flexible than ASICs, their utility is still limited in the face of ever-changing multimedia standards and applications. Programmable platforms are the most flexible way to extend the life of a product, but in order to break into the digital video technology market, they often require huge software development investments.
The primary challenge in digital video embedded applications is that the complexity of implementing video far exceeds that of simple image and audio compression and decompression. Digital video can take a variety of forms and formats, developers need to support complex configurations and a variety of different aspects, such as: different resolution / display size, different bit rates, real-time problems and even the reliability of video sources (such as , the difference between the video stream from the hard drive and the video stream from the wireless communication link). Even seemingly straightforward tasks -- such as efficient management of audio/video synchronization and reliable video transmission over IP networks -- can still leave developers nervous. While some devices are overwhelming for many application developers, they have to support multiple standards, including those that must be specified. To get a glimpse of the importance of this flexibility, just think about the rapid deployment and widespread adoption of H.264 video CODECs.
The main obstacle for many engineers is the lack of a digital video development platform with enough performance, low cost, high flexibility, and easy access. For engineers who want to integrate video in new applications, low-cost off-the-shelf video subsystems must be used to reduce the complexity of video design.
And with the DaVinci technology from Texas Instruments , all the problems can be solved!
What is DaVinci technology <br> <br> successful implementation of the latest advances in digital video requires four elements, namely: processors, development tools, software and systems expertise. With digital video, audio, voice and voice technology in a platform that integrates these four elements, DaVinci technology can lay the foundation for the current revolution in digital video.
DaVinci technology leverages TI's 25 years of digital signal processing and integrated circuit expertise to provide system-on-a-chip (SoC), which is optimized for flexible digital video implementations, with industry-leading performance and integration Programmable digital signal processor (DSP) core, ARM processor, and video acceleration coprocessor. With efficient processing power, memory, I/O bandwidth, balanced internal interconnects, and a combination of dedicated peripherals, DaVinci technology-based SoCs provide the ideal core power for video applications at the lowest cost.
The processor itself can only be used as the basis for a digital video solution. Managing all the components of a digital video system is an extremely complex engineering challenge. For many applications, digital video is just one of many components of a more complex system. Gone are the days when engineers arbitrarily invested a lot of time and money in self-consideration of basic technology.
In order to truly allow developers to overcome the initial obstacles and speed up the time-to-market process, it is not enough to develop only the basic chips and software for implementing digital video. Developers not only need processors, they also need ideal code that can be put directly into production. In other words, to meet the specific needs of their applications, developers also need hardware and software that has been integrated into a configurable or easily programmable digital video subsystem.
Just as the transition between assembly language and C language enables developers to fully develop more advanced functionality, DaVinci technology enables developers to get rid of the specific technical details of digital video. Developers no longer need to know the details of implementing a specific CODEC engine (such as MPEG-2, H.263, WMA9) in their video applications. With the API that allows developers to use the ideal CODEC without modifying the upper application code, we can significantly simplify the specific low-level details of video CODEC processing.
Getting rid of the CODEC is an important step in the widespread adoption of digital video. When developers can build on the functionality they have developed before, innovation has come to their eyes. For example, in the past when developing electronic devices, even the most basic functions required engineers to perform gate-level layout. For many years, TI and other companies have been committed to integrating functions in silicon chips, laying the foundation for devices that exceed their functional expectations, while reducing the amount of engineering required to achieve the desired goals. For example, the advent of DSP has driven decades of technological innovation by providing a computational engine that significantly speeds up signal processing tasks.
With DaVinci technology, TI can once again achieve a new level of innovation. It is the advent of DSP that brings computational acceleration, so DaVinci technology will provide application acceleration based on TI's DSP. Developers no longer need to understand the various mechanisms behind audio, video, video, and voice CODECs.
For developers who want to rely on the big tree of DSP, opportunities still exist. However, Da Vinci has made it an alternative, not a must. By providing software that can be put into production at any time, such as hardware drivers, manually optimized CODECs, and application code for managing audio/video synchronization and data streams in the network, DaVinci technology enables developers to achieve first-class knowledge without knowing how to program DSPs. Video features.
The complexity of the DaVinci technology platform to develop open way <br> <br> digital video system is mainly attributed to the many components developers need to create and manage. Writing code for many components and managing the interaction between them will greatly increase the difficulty of integrating a complete system.
DaVinci technology reduces system complexity by providing an open platform on which TI and its third-party partners have developed and integrated the various components needed to form a digital video system. And they also integrate the hardware and software needed to enable any engineer to implement digital video innovation.
The effectiveness of an open platform is unquestionable. For example, the open development platform for the PC market has triggered an explosive growth in the re-emergence of innovative applications. TI's OMAP platform environment has taken mobile phone application development to a new level - by integrating hardware and software, software developers can still leverage existing systems and focus on new markets and new revenue sources, such as developing text Information transfer, ringtone downloads, and other advanced applications in mobile phones.
DaVinci technology incorporates the OMAP environment concept into a wide range of digital video applications. At the chip level, TI's expertise and historical experience in video products enable it to develop highly optimized coprocessors and development tools to extend its chip-based DSP capabilities. However, developers don't have to worry about how to program and optimize code details for their basic innovations. DaVinci technology leverages these innovations through a combination of standard APIs that are easier to use - these APIs allow easy use of codecs that are ready to go, allowing developers to focus on developing maximizing added value The product comes up.
The open development platform provided by DaVinci technology also extends the application. DaVinci software will initially support Linux and will continue to support other operating systems in the future. Linux-backed content includes peripheral drivers, real-time application management, application-level APIs, and code that is ready to go. The integrated combination of integrated DSP-based, dedicated development tools, tuned drivers, CODECs, and system-level application code optimized for video enables developers to implement complete and complex digital video systems with a small number of function calls Codec function.
The world is changing, and the availability of digital video ready-made will certainly enable and inspire new applications that we have never heard of. However, innovation is only possible if engineers are concentrating on developing new ideas for using existing technologies without having to bother with those useless repetitive developments. DaVinci technology has achieved the intricate details behind digital video, and all engineers have to do is easily bring low-cost digital video to the consumer market.
