New family of network storage processors provides Mediabolic's Media Server software for streaming music, photo, and video files to PCs or other DLNA-compliant entertainment devices on the network.

MSP220x family provides a highly integrated, cost -optimized solution for wireline and wireless Network Storage and Networked Entertainment products

SANTA CLARA, CALIF. - - NOVEMBER 28, 2005 - - PMC -Sierra, Inc. (Nasdaq:PMCS) today announced the addition of network storage devices to its broad portfolio of Multi -Service Processor(R) (MSP) solutions. The new MSP devices - - MSP2200, MSP2202, MSP2204 and MSP2206 - - are storage -optimized processors integrating key features such as hard disk drive (HDD) controllers, while providing superior performance and significantly lower costs compared to general -purpose processors. Together with PMC -Sierra's advanced network attached storage (NAS) software and Mediabolic's DLNA -compliant media server software, the MSP220x family provides:

* a comprehensive solution, including processors, application software and product reference designs that allow ODMs and OEMs to rapidly deliver simple and affordable network storage products;
* the highest level of optimization and the smallest footprint for network storage processors available, including embedded HDD controllers, TCP/IP off -load and secure data encryption;
* simple file sharing, and enables multi -PC backup and digital media server applications for streaming media content to PCs or other DLNA -compliant entertainment devices on the network; and
* the ability to deliver entry -level products that can retail for less than $70 (without HDDs).

'The MSP220x family of network storage processors is a natural extension to our Voice -over -IP solutions for the digital home and office,' said Dino Bekis, vice president of marketing and applications for PMC -Sierra's Communications Products Division. 'The expansion of triple play -bundled services from carriers, along with the rapid growth of content -intensive applications such as digital music, photos, recorded TV shows and home movies, is driving the demand for easy -to -use storage solutions that must seamlessly integrate into home networks. Incorporating Mediabolic's software enables us to enhance our robust solution by allowing it to interoperate with a wide array of entertainment products.'

'PMC -Sierra's decision to incorporate Mediabolic's technology demonstrates the influence of centralized media server functionality in the adoption of network storage for the home,' said Michael Greeson, President of The Diffusion Group. 'Almost two -thirds of those that intend to adopt a home network are looking to connect these media -centric activities. TDG anticipates that by 2010, the total number of NAS devices in homes will exceed 15 million units. PMC -Sierra's MSP220x processor series is positioned to address this growth with a cost -effective offering for manufacturers.'

Covering the range from residential to Small Office/Home Office (SOHO) NAS applications, the MSP220x devices deliver superior performance and features at significantly lower system cost. This high level of integration delivers key features required for shared networked storage and media server applications such as: 10/100 Ethernet MAC, multiple HDD controllers, low -cost DDR SDRAM support, hardware acceleration for TCP/IP off -load, encryption and memory management, a USB port and real -time -clock.

'PMC -Sierra is bringing network storage processing to the next level with the addition of digital media distribution,' said Daniel Putterman, president and CEO of Mediabolic. 'With PMC's commitment to delivering high -end storage semiconductors, we can offer an advanced, 'always -on' media server storage platform with unparalleled price performance and a very high level of integration. The MSP 220x family will enable our shared OEM customers to shorten their development schedules and reduce their design risks while simultaneously giving them added product flexibility and customization.'
