MessageQ issues ARM->DSP0->DSP1->DSP2->DSP3->DSP4->DSP5->DSP6->DSP7->ARM link

Rao Munzir

Hi,

I want to establish a link using MessageQ like  ARM->DSP0->DSP1->DSP2->DSP3->DSP4->DSP5->DSP6->DSP7->ARM

But couldn't see any example like that. only example that is a little related to it is image processing demo.  that has communication flow like that.

ARM<->DSP0

ARM<->DSP1

ARM<->DSP2

ARM<->DSP3

ARM<->DSP4

ARM<->DSP5

ARM<->DSP6

ARM<->DSP7

So I decided to do something like that

ARM->DSP0->ARM->DSP1->ARM->DSP2->ARM->DSP3->ARM->DSP4->ARM->DSP5->ARM->DSP6->ARM->DSP7->ARM.

But when Itry to that I got 2 problems.

1- Most of the time Not a single message is received at any DSP.

2- If messages are received, after a certain number of messages next message are not received.

Attaching code and cfg files. I have gone through 3-4 IPC examples but nothing like that is implemented .

Regards

    Hi Rao,

    With reference to this link, e2e.ti.com/.../367381, the processor SDK 2.0.2 was not available . BUt now, Processor SDK 2.0.2 is available which has the following list of IPC examples.You will find it under IPC 3_42_00_02.

    1. ex44_compute,

    2. ex02_MessageQ

    3. ex45_host

    4. ex46_graph - Consumer-producer example.

    Out of these examples, you can refer ex44_compute.

    1. ex44_compute  example - In this example, the IPC happens between ARM-DSP0, ARM-DSP1, ARM-DSP2...... upto ARM-DSP7. This example will be suitable for your experiment.

    The following is the output log which shows the communication between ARM to other DSP cores.

    Does it have DSP-DSP communication too?

    Hi Rao,

    In example, ex46_graph, combinations such as ARM-DSP0, DSP0-DSP1, DSP-ARM and lot more combinations are demonstrated as a Producer-combiner-transformer-consumer

    In this example, you can use any DSP cores and communicated between DSP- DSP, DSP-ARM, ARM-DSP etc.

    These are the combinations I tried and it worked for me.

    I have attached the steps on how to run this example on the target. For compiling this example, you can refer to the readme.txt enclosed insise the package./cfs-file/__key/communityserver-discussions-components-files/791/6505.ex46_5F00_log.txt
