TDA4VM: some questions

Part Number: TDA4VM

Hi team,

1) What is the SDE disparity output scale value? Checking the value after disparity, the value is large and should have been multiplied by a scale value. 

2) The PTK SDE demo has added a three-layer golden tower version, can it directly output the disparity output? Configuring output in config does not take effect. Is it required to add output logic manually? 

3) Camera Access Adapter: How to access the I2C bus? How to access the daughter board deserializer? How does CSI_RX_if configure the virtual channel? Is there any routine for reference? 

4) DSPLib: Is the code that calls the control DSP module running on arm-A72? Where is the input and output data of the DSP unit stored in memory? 

5) Can DSP and MMA modules pass data directly through pointers? 

6) What libraries do we need to use if all the hardware units (including various peripherals and on-board hard core acceleration modules) use the calling method of the SDK directly instead of OpenVx? 

Could you help check the remaining questions? Thanks.

Best Regards,

Cherry

  • Hi ,

    Could you please start a new question for each of the above list of questions? so that it can be assigned to correct expert.

    3) Camera Access Adapter: How to access the I2C bus? How to access the daughter board deserializer? How does CSI_RX_if configure the virtual channel? Is there any routine for reference? 

    You could use Board APIs to access I2C. This is same mechanism used in imaging layer. You could refer to IMX390 or any other sensor driver in imaging/sensor_drv/src folder. 

    Regarding virtual channel, please use CSIRX driver and provide virtual channel in virtChan parameter. Driver appropriately configures it the HW.
