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


"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 Evaluation Kit

DIDO Evaluation Kit is a carrier board designed to host DIDO SOM. NAON Evaluation Kit is a development/test system designed to start working with the NAON platform and experimenting with the implemented features. The carrier board can be used also to start working with NAON and MAYA modules.



Kit Contents

NAON Embedded Linux Kit is composed by the following content:


  • NAON Evaluation Board

  • DIDO CPU module (part number: DOFx)

  • U-Boot bootloader (source code and binaries)

  • Linux operating system (source code and binaries)

  • Full NELK documentation (Manuals, User's Guides, Application Notes, Carrier boards schematics, Mechanical Drawings...) included in the uSD card
  • complimentary access to DAVE Embedded Systems' DIDO RESERVED AREA

  • Periodic updates (documentation revisions, new Application Notes, new Design notes)

Available Features

DAVE Embedded Systems is committed to provide customers with solutions which simplify the start up phase and accelerate the Time 2 Market. For this reason, additionally to HW services, also on software side many solutions are provided. These solutions are below listed and described in detail on the WIKI web site.

Linux O.S.:


DIDO SOM is specifically designed for Linux O.S. DAVE Embedded Systems provides a complete Board Support Package with all drivers. These BSP is designed starting from the Texas Instruments SDK releases for DaVinci DM814x/AM387x. This evaluation kit is unified with MAYA and NAON SOMs HERE you can find more information.

Android O.S.:


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.


Software Updates - LONG TERM SUPPORT

DAVE Embedded Systems is committed to provide updated software along the life cycles of its products. This is possible maintaining products aligned with Silicon Vendor releases. Additionally to this othe bug fixes are committed and published on GIT server. More information on how to have access to this are available HERE
