esp32_mmd's Issues

Is there an option for a DMA driven QuadSPI or 8-bit parallel solution for better framerate?

Hello.
I'm considering using a DMA-driven QuadSPI communication with an LCD display or a video driver at 80MHz or an 8-bit parallel bus on the sequentially arranged GPIO pins so that the performance doesn't suffer and so that a very powerful 3D game engine akin to Spyro 2 for PS1 or Driver for PS1 could be made.

This is my idea:
http://www.vsdsp-forum.com/phpbb/viewtopic.php?f=14&t=2353&p=12464#p12449

The display in question would be a parallel ILI9341 and the video driver in question would be VS23S040. If the 80MHz is too fast for QuadSPI or if QuadSPI isn't available for that display and that video driver, I would like to consider TinyFPGA that converts QuadSPI communication to 8-bit parallel communication.

Could you try one of those approaches and tell me what the maximum framerate would be?
