TDA2: Data Flow in TDA2x

Shruti Joshi

Part Number: TDA2

Hello,

We are trying to understand the data flow in TDA2x.
We have the following queries:
1. How data and control are given from IPU0 to DSP/EVE and vice-versa?
2. How does data handling happen between DSP and EVE?
3. In which layer do these communications take place in Vision SDK?
4. Through which physical interface(hardware component) does this data transfer happen?
5. How does mailbox work?

Regards,
Shruti

Hi Shruti,

Please refer to Vision SDK architecture documents present in PROCESSOR_SDK_VISION_03_05_00_00\vision_sdk\docs\Architecture.

Hi Rishabh,

Thank you. I found the answers to most of the questions in the documentation present. Still, I did not find out about the following:
4. Through which physical interface(hardware component) does this data transfer happen?

Can you please help me find them?

Regards,
Shruti

Hi Shruti,

There is no physical interface as this is internal to SoC, the communication is using IPC where messages contain buffer pointers.
