Linux/TDA2E-17: target DDR3 memory size of 3D SV DEMO in Vision SDK

Part Number: TDA2E-17

Tool/software: Linux

Dear Champs,

My customer is investigating TDA2EG-17 for 3D SV, and want to estimate DDR3 memory size.

Could you please check and let me know the estimation of DDR3 memory size?

Target requirements are

- 1MP camera 

- 2MP display after merging 4ch input image

- transparent mode

Thanks and Best Regards,

SI.

  • Hi SI
    which is the customer here?
    we can provide the data WRT TI 3D SRV, but this data may change if they use their-own (customized) Alg

  • Hi Shiju,

    I understand and it would be enough.
    Could you please provide the data WRT TI 3D SRV?

    Thanks and Best Regards,
    SI.
  • Hi SI
    OK, i will provide this data early next week

  • Hi Shiju,

    Thanks for your estimation.
    Could you please provide details what are the belows? what are stand for?
    - Galign3D
    - Palign

    And I found 'SRV Calibration',
    Do you mean this is 'Auto Calibration' running on SRV operation?

    And for '(no Graphic/overlay layer is considered)',
    Is this for Display, right?

    Thanks and Best Regards,
    SI.
  • Hi SI

    Answers inline

    Could you please provide details what are the belows? what are stand for?

    - Galign3D

    [Shiju] - Galign3D – look up table (LUT) for geomatics alignment


    - Palign
    [Shiju]- Palign – LUT for photometric alignment


    And I found 'SRV Calibration',
    Do you mean this is 'Auto Calibration' running on SRV operation?

    [Shiju] yes

    And for '(no Graphic/overlay layer is considered)',
    Is this for Display, right?

    [Shiju] yes
