Hello all,
I've recently acquired this board:
Don't let the name fool you: AI is not the only thing this board is good for. In fact, it really doesn't have any specialized AI hardware at all. It's really a signal-processing platform.
It has a dual-core Cortex-A15, two C66x DSPs, 4x PRUs (32-bit microcontroller cores for real-time control), 2x dual-core Cortex-M4s, and several graphics acceleration units.
That's a whole lotta horsepower for $130. Combine this with any of the inexpensive USB-interfaced RF hardware and you've got a lot of possibilities for the determined amateur.
I plan to make this the core of my SatNOGS setup, with all control and processing done on this board, relaying directly to the SatNOGS DB.

The embedded Vision Accelerators aren't really graphics accelerators. They do some important things for DSP that we could potentially leverage, but I haven't been able to tell in short look if they are actually documented so that you can program them, or just are hardware accelerators for a proprietary thing they call Vision pack. See https://ieeexplore.ieee.org/document/6865062

The EVE is optimized to deal with pixel data, which could be input or output. From the paper you cited:
"ARP32, a 32-bit RISC core, is the master controller and programmable frontend of EVE providing the user a full ANSI-C level programming environment complete with state- of-art solution for debug and tools support for easy software development. "
"VCOP (shown in Figure 2), the Vector/Vision CO- Processor, is an 8-way SIMD engine with two parallel and identical functional units (FUs) per SIMD lane. "
You're right in that it doesn't draw circles, do fills, etc. as primitive operations.
When I speak of AI, I mean hardware Convolutional Neural Networks (CNNs), like this:

Zach,
I worked on a projector controller interface once that was based on the beagle bone black (cerca 2016). Nothing too fancy, mostly an ETL job between ethernet / serial devices, with a web UI for control... But yeah, those are some useful boards. For little projects now, I use the teensy-lc.

I worked on the original Pixar Image Computer from which all subsequent SIMD image architectures are derived. About 35 years ago now. A lot of what the application sheet talks about is driver augmentation, which is mostly formatting camera data for display using the Porter-Duff image algebra, what video folks know as "compositing". The SIMD cores would be usable as vector processors for DSP.
