The Texas Instruments DaVinci Technology combines TI's offering of digital signal processing chips, software, tools and support for developing a broad spectrum of optimized digital video end equipments. The DaVinci DSP is part of the popular TMS320 DSP family.


A typical multimedia system such as a digital video recorder or digital camera can be split roughly into two pieces: control and media. The control portion handles tasks such as memory card or hard disk access, user interface, and networking, while the media portion covers tasks such as encoding and decoding of audio and video. A general-purpose processor performs well in control tasks, but only the fastest of these processors are sufficiently powerful for intensive media-related tasks such as real-time, high-quality video encoding. A DSP, on the other hand, is superb at the repetitive, easily parallelizable media-related tasks, but usually performs poorly in control-related jobs.

The idea behind the DaVinci family of processors is that by using both a general-purpose processor and a DSP, the control and media portions can both be executed by processors that excel at their respective tasks. The integration of these two components into one chip simplifies the system design and allows for more efficient communication between the two components.

The DaVinci family of processors now scales from multiple core devices (e.g. DM644x) to single core DSP devices (e.g. DM643x) to single core ARM devices (e.g....
