Excerpt: alphaWorks is IBM 's 'emerging technology portal'. It is a web community for early adopters to preview and collaborate on prototype technology from IBM Research labs. alphaWorks was founded in August 1996, in IBM's Advanced Technology group (called 'Internet Division' at the time). The alphaWorks program has launched early release technology implementations in nascent technology communities of software developers, in areas like Java technology, XML and web services . Since 1996, alphaWorks has succeeded in helping IBM connect with innovative developers to lead the development of promising new standards, products and open source technology. alphaWorks is a key aspect of the developerWorks resource for developers.

Semi 's PWRficient PA6T. AltiVec is a trademark owned solely by Freescale, so the system is also referred to as Velocity Engine by Apple and VMX by IBM and P.A. Semi, although IBM has recently begun using AltiVec as well. While AltiVec refers to an instruction set, the implementations in CPUs produced by IBM and Motorola are separate in terms of logic design. To date, no IBM core has included an AltiVec logic design licensed from Motorola or vice-versa. AltiVec is a standard...
