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:
