Germany's Infineon has licensed microprocessor designs from MIPS Technologies for building voice over Internet (VoIP) chips. Infineon's INCA-IP chip is a single piece of silicon that contains most of the necessary components for building VoIP phones, including an integrated encryption engine for enhanced security. Besides phones, the chip gets incorporated into wireless microphones and headsets.
MIPS, originally part of server maker SGI, competes against Cambridge, England's ARM and Hitachi in licensing microprocessor designs to companies that can't afford the time or energy to design chips on their own. The chip is primarily known for its ability to consume little energy.
