For a relatively new design, the GreenArrays chip is highly unusual: 1) Asynchronous logic. 2) Stack machine design. 3) Extremely limited memory per cell. 4) 18-bit words. 5) No MMU. Chuck Moore gave a nice presentation on applications and his rationale here: https://www.infoq.com/presentations/power-144-chip https://www.infoq.com/presentations/power-144-chip I thought it was pretty neat how in some of his design docs, a column of async cores are used as a memory controller.
