LONDON – Calxeda Inc., a developer of ARM-based processors and software for low-power servers for data centers, has announced it has raised an additional $55 million in equity funding. This is one of the largest semiconductor investments of 2012 and puts the total raised by Calxeda over $100 million since the company was founded as Smooth-Stone in 2008.
The latest funding has been led by Austin Ventures and Vulcan Capital with participation by existing investors. Existing investors include: ARM, Globalfoundries owner Advanced Technology Investment Co. (ATIC), Battery Ventures, Flybridge Capital Partners, Highland Capital Partners.

Calxeda (Austin, Texas), which now employs over 100 people, said the money would be used to accelerate the adoption and innovation in the low-power server market. Calxeda is already supplying its EnergyCore server chips to Boston Ltd. (St. Albans, England) for inclusion in Viridis servers.
Performance and power measurements conducted by Calxeda and others show that Calxeda technology delivers up to a ten-fold improvement in energy efficiency compared to "commodity" x86-based servers, Calxeda said.
"Businesses require a more efficient solution for the Web, Cloud, and Big Data. That is what Calxeda is now delivering and this funding will enable us to go bigger and faster," said Barry Evans, co-founder and CEO of Calxeda, in a statement.
"In the time since we first met Calxeda, they have executed exceptionally well, and the market has begun to embrace disruptively power-efficient datacenter architectures," said Clark Jernigan, a partner at Austin Ventures.
Calxeda is included in version 14.0 of the Silicon 60 list of emerging startups published by EE Times. The company entered the Silicon 60 at version 12.0 in April 2011.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
