Questions about C6A8168

Other Parts Discussed in Thread: OMAP3530, DM3730

Hello list,

I start working on a new design for embedded s/w defined radio testbed. From the comparison, C6A8168 is more powerful than DM3730 and OMAP3530.

Currently, I am studying some popular reference designs based on DM3730 and OMAP3530.

I just wonder, to migrate to C6A8168, would that require a big software effort?

What is the XDS JTAG emulator to be used to take full advantage with C6A8168?

Thank you for your help.

Regards,

Alex

    Alex,

    Several XDS emulators can be used, including the XDS560v2, XDS100 and XDS510USB.

    Marc,

    Thanks for the XDS emulator choices.

    Just wonder if you would provide us some hints on how much gain and difference in between C6A8168 and DM3730/OMAP3530.
    Few questions would be:
    1. How is the performance gain between the DSP core of C6A8168 vs. DM3730? (more concern on floating vs fixed-point, beside frequency difference)
    2. How is the difference in terms of ARM migration? (e.g. registers, peripherals, etc)
    3. How is the difference in terms of DSP migration? (From datasheet, it is said it is compatible.)
    4. Any sample available, and what is the ARM and DSP frequency?

    We would like to estimate how much gain and how much effort to be prepared, if we proceed with C6A8168.

    Regards,

    Alex

    Alex,

    We do not have migration docs as of today, but we will be looking at creating a migration doc in the future.  The difficulty of migration depends a lot on the level at which you are doing your programming.  For example , the ARM and DSP migration should have minimum impact provided the existing DM3730 SW doesn't rely on specific internal processor architectural details (L2 size, instruction set, on-chip RAM size, etc.)  The peripheral sets match fairly closely and they are abstracted at the PSP layer.  However some SW changes will be required as it relates to PSP differences, memory map differences, etc.   Looking at the first section of the two datasheets will give you a good indication of the HW differences between the two devices, and the frequencies supported.  Samples are available now.

    Regards,
    Marc

    Hi,

    I have installed TI CCS 4.2.3, and use Spectrum Digital XDS560v2. In CCS, 'Target Configuration File' is created, and I can't find C6A816x device. How to add new device in CCS 4.2.3? Does TI or Spectrum Digital provide the device?

    Thanks!

    I'd assume that for the C6A816x you will have to switch to CCS v5, for downloads see here:

    Code_Composer_Studio_v5

    P.S. Maybe you'll have to look for TI816x instead of C6A816x. Did you?

    Hi,

    I have installed CCS 5.0.3, and use TI816x instead. It works. Thanks for your help.

    Marc,

     

    Thanks for your answer.

    Can you advise where I can buy C6A8168 samples?

    Marc,

     

    How do I know the device speed range of TMS320C6A8168ACYG2 ?

    Check your link and Asia, America and Worldwide have no stock. Can you advise other channels?

     

    Regards,

    Alex,

    The Device Nomenclature figure at the end of the datasheet explains the different parts of the device name.  This device's speed range is 1.2-GHz ARM and 1.0-GHz DSP.

    I'm not sure about device availability - you will need to contact your local TI Representative for that.

    Regards,
    Marc

    Marc,

    Notice the nomenclature. I shall approach my local TI distributors.

    For C6A8168 and DM8168 (both are ACYG2), are they pin-to-pin compatible?

    From the overview, the paper difference I observed is in HDVICP2 Video Accelerator (none vs 3). Are there other differences that I overlook? May I assume that both are architectural equal in terms of ARM, DSP and other standard integrated peripherals? Both are device range 2, so sharing same ARM, DSP and SGX frequencies.

    Do you know about the product schedule of C6A8168 speed range 5? i.e. 1.5-GHz ARM and 1.25-GHz DSP.

    Thank you for your help.

    Regards,

    Alex

    Alex,

    Yes, they are pin compatible with the same frequencies.  As you noticed, the difference is that the DM devices have the HDVICP2 Video Accelerators and the C6A devices do not.  I am not sure at this point when the range 5 devices will be made available.
