SAN JOSE, CA Embedded Systems Conference Booth #1929 and #2118, April 16, 2008 — Sun Microsystems, Inc. (NASDAQ: JAVA) and Wind River Systems, Inc. (NASDAQ:WIND) today announced that Wind River will port its Carrier Grade Linux (CGL) and Workbench development suite to Sun's UltraSPARC T2 chip multithreading (CMT) processor. Wind River Platform for Network Equipment, Linux Edition, will be the first carrier grade Linux for Sun's CMT processors. With this announcement, Sun and Wind River will be providing the networking industry with a fully integrated, optimized and tested solution of the industry's leading multicore processing hardware and CGL, enabling companies to quickly develop and deploy next-generation enabled networking applications. Sun's Netra Carrier Grade rack servers and ATCA blades will be the first CMT systems to run Wind River Carrier Grade Linux.

"Sun has taken an important step today in becoming a mainstream processor vendor for the embedded market," said Mike Knudsen, vice president of marketing for Sun's Microelectronics unit. "The embedded industry is at the cusp of a shift toward CMT architectures, and Sun is poised to be a serious player in that market. Today is a milestone in our emergence as a processor vendor to the broader industry."

"Today's device designs demand more processing power, higher reliability, and increased application intelligence," said John Bruggeman, chief marketing officer for Wind River. "Combining Sun's CMT processing technology with Wind River's industry-leading Carrier Grade Linux platform and tool suite for multicore application development, delivers a solid foundation from which device software developers can design smart, high-performance applications with a competitive edge."

CMT and Embedded Market
With today's announcement, Sun can deliver the benefits of CMT processor technology to embedded systems designers, enabling them to increase system throughput performance by as much as three times compared to competing, network-based processor designs. CMT also dramatically lowers processor parts counts by a third or more and cuts power and heat emissions.

In August 2007, Sun introduced the UltraSPARC T2 processor, the world's fastest commodity processor. An eight-core, 64-thread processor, the UltraSPARC T2 is powered by less than 95 watts (nominal) with less than two watts per thread, boasts the most functionality, and lowest wattage per core and thread of any processor in its class.
