“DAVINCI” DM814x – DIDO

Processor:  Texas Instruments "DaVinci" DM814x

DIDO is a ready-to-use CPU module based on Texas Instruments DM8148 high performance application processor. DIDO is the first product of DAVE Embedded Systems' ULTRA Line, which includes best-in-class solutions and full featured SOMs. In particular, for DIDO this means a boost on performances, thanks to the 2 GB DDR3 @ 533 MHz SDRAM memory, and great versatility thanks to the integrated PCI Express interface. DIDO is designed to be easily included in customer's embedded systems, due to the small form factor, the inexpensive stacking connectors and the back-compatibility with DAVE Embedded Systems' NAON CPU module.

Longevity program: Texas Instruments General Quality Guidelines

DAVE Embedded Systems is committed to support and maintain its products according to Texas Instruments General Quality Guidelines

20: PRODUCT WITHDRAWAL/DISCONTINUANCE

"TI’s Product withdrawal/discontinuance process complies with JESD48, latest issue. TI makes an effort to not obsolete products out of convenience. Convenience means: low running device, poor yields, limited customer adoption or similar items. TI’s obsolescence withdrawal schedule provides a longer lead time than the industry standard. TI allows 12 months for the last order and an additional 6 months to take final delivery of obsolete items. In rare circumstances, an accelerated withdrawal schedule may be necessary. In such cases, TI will communicate the last buy and final delivery dates in the EOL notice, along with an explanation of the circumstances necessitating the early withdrawal".

DIDO SOM is also able to run Android O.S. DAVE Embedded Systems provides some example of a basic Android environment with some functionalities available on board. This solution is provided turn key without source code release. HERE you can find more information.

 

Power consumption optimization

DIDO SOM has a very rich architecture useful for many video and big data manipulation. With this platform it is possible to encoded full HD video streams (1080p60) with a reduced power consumption. For these reasons, very often it is necessary to control and manage the power consumption. HERE you can find more information.

 

Video Input Latency optimization

DIDO SOM is specifically designed for video manipulation. Thanks to parallel dual video input capabilities it is possible to capture and encode video frames in real time. Glass to Glass latency it is a very actual topic for this platforms. DAVE Embedded Systems team has worked deeply on this feature. HERE you can find more information.

 

Software releases

DAVE Embedded Systems is committed to provide an easy to use solution for start the evaluation. All the system setup is pre-configured in a DAVE Embedded Systems Virtual Development Kit. The DAVE Embedded Systems DVDK is a virtual machine, based on Oracle VirtualBox that allows developers to start using DAVE Embedded Systems' platform without wasting time in installing the development environment. HERE you can find more information.
