Hello,

The GPU shares the memory (DDR) with the rest of the system. OpenGLES and EGL API are used to program the GPU. The QNX GPU driver is provided by QNX and we recommend reaching out to QNX for specifics.

Hi Yao,

Could you take a look at section 6.7 of the TRM which gives details about the GPU hardware capabilities? https://www.ti.com/lit/zip/spruil1

For questions at the board level such as how much DDR is available on the EVM, I would recommend reading: www.ti.com/.../spruis4d.pdf

Let us know if there are additional questions that are not addressed by these documents.

Regards,

Takuma
