DRA756: What is the relationship between DRA75x, TDA2x and Jacinto 6?

Part Number: DRA756

Hi all,

I'm completely new to TI hardware and I've been told to run deep neural networks on the c66x dsp of Jacinto 6.

After I searched online, I found that the processor of a Jacinto 6 is DRA756. But it seems that TIDL is only included in the vision SDK of the TDA family.

Now I'm confused what is the relationship between DRA75x, TDA2x and Jacinto 6? Is TIDL and usage of deep neural network possible on the c66x dsp of Jacinto 6

Moreover, how to develop such deep neural network on c66x on a linux desktop? For example, can I use CSS and how to include the vision SDK and emulate the hardware environment? If this question is appropriate in this forum, then which forum should I go to?

Many thanks,

Will

    Hello Will,

    Absolutely, here is the correct place to raise such questions and we are happy to assist. 

    Jacinto6 (J6) is basically the platform over which all these current/contemporary chips are built upon. DRA7xx and TDA2xx are both Jacinto6 platforms. DRA7xx is targeted for Automotive Infotainment use cases, while TDA2xx is targeted for ADAS (Advanced Driver Assistance Systems) use cases. Bith devices have different levels of ASIL/safety. They also have differences here and there, which you can find if you compare the 2 Data Manuals/datasheets (for the most part check the device comparison table). Now, the "xx" are for the different paper spins of these devices. So, you have all these choices of a whole bunch of chips with different features to choose based on your needs. Again, check the data manual (DM)/datasheet and the technical reference manual (TRM) found on the product page.

    You can also get started with Vision SDK and CCS. You will need the EVM/board, emulator JTAG debugger, and CCS installed. All software is free. You can download CCS from here http://processors.wiki.ti.com/index.php/Download_CCS  and Vision SDK from here http://www.ti.com/tool/PROCESSOR-SDK-TDAX. After you have installed vision SDK there is a folder with documentation that you can study. You can start from the VisionSDK_Getting_Started_Guide and the VisionSDK_UserGuide to get you up to speed with the environment. From there, I'm sure you will be able to dig further into your use case (neural network).

    Hope it helps,

    Thanks,

    Alex

    Thank you Alex! I'll have a look at those suggested documentations.
