64bit processors run latest
version of Windows CE
NEC and MIPS Technologies have announced that the new Microsoft Windows CE Talisker Beta 2 operating system includes 64bit support
Microsoft announced the availability of Talisker Beta 2 on 13th August 2001. Jointly sponsored by the three companies, the latest version of Windows CE will take full advantage of the capabilities of NEC's high-performance embedded line of 64bit MIPS-based processors. Talisker Beta 2 technology is also fully compatible with the industry's only licensable 64bit embedded processor architecture and cores available from MIPS Technologies.
"The demand for high-performing Windows-Powered multimedia devices continues to grow, and Microsoft, NEC and MIPS Technologies are committed to providing the technology to meet this need", said Keith White, senior director of marketing for the Embedded and Appliance Platforms Group at Microsoft Corp.
"The combination of Talisker's rich multimedia functionalities and NEC's 64bit MIPS-based embedded chip offerings will enable OEMs to deliver high-performing Windows CE-based set-top boxes and other data-intensive smart devices".
The Microsoft Windows CE operating system, which includes the Platform Builder comprehensive toolkit for building Windows CE-based OS images, offers a compelling platform for creating high-performance consumer products because of its rich multimedia functionality and other features that enable designers to build smart devices that run Windows applications and connect to the Internet.
Embedded processors based on the MIPS architecture, including those manufactured by NEC, offer an innovative combination of hardware floating-point unit, 64bit data, graphics extensions, SIMD (single-instruction, multiple data) support for streaming video and audio, and deep, multi-issue pipelines.
By processing more than one instruction per clock cycle, multi-issue CPUs allow system designers to reduce CPU clock frequencies to achieve a required level of performance.
Minimising the clock speed greatly simplifies OEM design and testing tasks while greatly reducing power dissipation and electromagnetic and radio frequency interference.
Microsoft has optimised Windows CE to take advantage of these processor capabilities.
NEC's family of high-performance 64bit embedded chips for digital consumer, office automation and internetworking applications includes the VR5432 and VR5000 processors, and NEC's newest processor, the VR5500.
The VR5500 chip is rated at an impressive 600 dhrystone 2.1 MIPS at 300MHz.
Such performance and power efficiency (2.0 D-MIPS/MHz) result from its dual-issue, 10-stage pipeline.
System designers would have to use a 500MHz processor to achieve this level of performance with other processor architectures.
NEC's processors are now fully supported by the Windows CE operating system and development tools.
MIPS Technologies' long-established 64bit architecture and low-power, high-performance MIPS64 20Kc and 5Kf processor cores are licensed by semiconductor companies and system OEMs.
MIPS-based designs are found in embedded systems that meet the growing demand for high-quality 3D graphics and streaming media in a variety of applications, especially consumer products such as Internet appliances, set-top boxes and high definition TVs.
