Other Parts Discussed in Thread: TMS320DM8168

Hi all ,

I am using DSPC-8662-PCXE board having quad TI TMS320DM8168 SoC.

How we are communicating one TMS320DM8168 with the other TMS320DM8168 .

Please guide me as I am new with this hardware .....

    Hello,

    I checked DSPC-8662-PCXE Datasheet; I am not sure, but it seems that DM816x chips here are used for parallel encode/decode and normally they won't communicate with each other (no data nor configurations are passed from one to another). They are connected with two PCIe lanes each to x8 port and it seems that it is all about the PCIe device on the other side.

    Thanks Vladimir for your reply.

    But my doubt is if We see the TRM of DM8168 EVM board.

    There are 3 HD Video Image Coprocessors are there.

    And on this DSPC-8662-PCXE having total 8 channels ( HD Video Image Coprocessors ??(Please comment on this)).

    According to Doc of DSPC-8662-PCXE as you are mentioning that we can't communicate the one DM8168 with other.

    As Keystone architecture having Hyperlink to communicate with the other processor on that board is there any facility like this ??

    I am totally new to this hw ,Please do the reply and comment on my understanding ...

    Hello,

    What do you need to know about the multi-channelling? Why is such the number of the channels? It is mainly a design solution, I guess.

    I am not aware of such utility here that provides such communication between the chips. What is the application of  that type of communication? You can discuss the application with you local field engineer, and choose among the available technologies.

    BR
