Description

Design and implement a self-contained video microcontroller system, with the following Hard requirements:

* No additional processors or PCBs
* Teach myself verilog
* 480p video support, HDMI and/or other LCD interface
* 60fps video
* Single screen-style NES background
* NES-level sprite support
* 16-bit color

Stretch Requirements:

* 720p video support
* Super Mario Bros 3-level background scrolling
* Super Mario World-level layer support
* SNES-level sprite support
* 24-bit “true” color

The folks at Seeed Studio released an “Arduino Shield” that they call the Spartan Edge Accelerator. The board has a Spartan 7 xc7s15 and an ESP32. Seeed doesn't support using the ESP32 as an application processor, but I want to do it anyway.
