a2o
The A2O core was a follow-on to A2I, written in Verilog, and supported a lower thread count than A2I, but higher performance per thread, using out-of-order execution (register renaming, reservation stations, completion buffer) and a store queue. It is now being updated for compliancy and integration into open projects. (by OpenPOWERFoundation)

Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

iCE40 power consumption question
You can probably extrapolate from the numbers here.

Using an FPGA for low-power device with fast image acquisition
Aside from the points that /u/captain_wiggles_ pointed out, this is an application which ice40 FPGAs were actually designed for. They are low power (example) and have some features specifically designed for video applications, such as (sub)LVDS inputs and "outputs." Depending on your specs, one of these FPGAs could be a good choice (and you get a nice FOSS toochain as a bonus).
What are some alternatives?
When comparing a2o and ice40_power you can also consider the following projects:
