Calxeda

Calxeda was an Austin, Texas semiconductor startup — founded in 2008 as Smooth-Stone by Barry Evans, Larry Wikelius and David Borland — that built ARM-based EnergyCore system-on-chip server processors (ECX-1000, ECX-2000/Midway) aimed at low-power, high-density data center workloads. It raised roughly $90-103M from venture investors including Battery Ventures, and its silicon shipped in Boston Limited Viridis appliances and HP Project Moonshot systems. Calxeda ceased operations in December 2013 after a refinancing round fell through, and its ARM server IP resurfaced under Silver Lining Systems in December 2014. The company published no public API, developer portal, or machine-readable API artifacts, and calxeda.com is now a parked domain listed for sale, so there is no live API surface for the API Evangelist network to catalog.

Calxeda is profiled on the APIs.io network. Tagged areas include Company, Semiconductors, Hardware, Servers, and ARM.
