P.A. Semi Signs Power Architecture License

P.A. Semi Creates PWRficient™ Processor -- A Low-Power, High-Performance, 64-bit Scalable Multicore Processor Based on Power Architecture™

SAN JOSE, CA -- (MARKET WIRE) -- October 24, 2005 -- FALL PROCESSOR FORUM -- P.A. Semi, a Silicon Valley startup developing the high-performance, low-power-consumption, PWRficient™ processor for high-performance computing and embedded applications, today announced that it has secured a Power Architecture™ license from IBM. Under the agreement, P.A. Semi has licensed the rights to design, manufacture, and sell processors that fully comply with current and future versions of the Power Architecture for the development of its PWRficient processor family -- a low-power, high-performance 64-bit scalable processor -- also announced today.

"We chose to develop our PWRficient processor on the Power Architecture because of its scalability, high-performance capabilities, and robust community of developers," said P.A. Semi co-founder, president, and CEO Dan Dobberpuhl. "As a founding member of, our plan is to foster an evolving partnership with IBM and the Power community that will drive innovation now and well into the future."

"The high-performance, low-power PWRficient processor designed by P.A. Semi further underscores the scalability and flexibility of Power Architecture technology," said Tom Reeves, vice president, Semiconductor Products for IBM Systems & Technology. "Helping to facilitate this type of innovation by P.A. Semi in Power Architecture is exactly why we created We'll continue to work closely with P.A. Semi and other stakeholders within to inspire future advancements that extend Power Architecture processor technologies."

The first P.A. Semi PWRficient processor, a dual-core, high-performance, low-power chip, which is based on the latest version of the Power Architecture, delivers up to a tenfold increase in performance-per-watt numbers over other chips. P.A. Semi will work closely with IBM to integrate Power Architecture improvements into future versions of its PWRficient processor. This will help ensure that the enormous software ecosystem will easily migrate to the P.A. Semi PWRficient processor family.
