TDA4VM-Q1: GPU internal memory

Part Number: TDA4VM-Q1
Other Parts Discussed in Thread: TDA4VM

Hi, Expert ,

We have encountered some issue on DDR bandwidth. So We want to use the GPU internal memory to store the the frame buffer.  

Can you pls help to check if the TDA4VM GPU internal memory is available ?  Thanks. 

Regards,

    Hello.

    The GPU does not have an internal memory (other than internal buffer it utilizes by default and this cannot be changed). The only memory available to the GPU is shared memory with the rest of the system. The recommendation is to analyze application bandwidth and try and reduce the application memory usage.

    For example:

    Use lower complexity geometry, lower resolution textures, try and minimize the number of variables passed between vertex shader and fragment shader - etc.
