The new VIA Eden processor family boasts an ultra-efficient architecture, world-class 90nm production and the highly efficient VIA V4 bus interface for unprecedented passively-cooled, ‘fanless’ performance.

Scaling from 400MHz to 1.2GHz within a maximum power envelope of 7W, the VIA Eden processor offers impressive power efficiency and highly effective heat dissipation all within an ultra compact NanoBGA2 package measuring just 21mm x 21mm. When combined with the most recent VIA C-Series digital media IGP chipsets, which have been designed as companion sets for the latest VIA processors, system developers can utilize an impressive range of features for a wide range of desktop and embedded applications.

VIA Eden ULV Processors

The Ultra Low Voltage (ULV) additions to the Eden processor family set new standards in performance per watt; scaling from 500MHz to 1.5GHz, achieving unprecedented speed for a fanless x86 processor within a maximum power envelope of just 7.5 watts. By enabling a range of ultra small, ultra quiet devices and featuring a unique architecture that enables high performance with low power and cool temperature operation, the VIA Eden ULV series gives system designers the building blocks to create innovative products and open up new markets.

The 500MHz VIA Eden ULV processor especially, with its maximum operating power of just 1 watt and idle power as low as 100mW, VIA has made the x86 architecture more accessible than ever before to the embedded market. Read more about it in this white paper.

Leading Power Efficiency and Low Power Consumption

The new VIA Eden processor is based on the advanced VIA CoolStream™ architecture of the 90nm ‘Esther’ core that minimizes power consumption within an ultra compact die while optimizing performance, making it an ideal solution for a wide range of business, industrial and commercial systems. Consuming as little as 500mW (0.5W) idle power and a maximum thermal design power (TDP) of no more than 7.5 watts at 1.5GHz, the VIA Eden processor also features VIA PowerSaver technology to reduce processor power draw. With its low profile nanoBGA2 package measuring just 21mm x 21mm, the VIA Eden processor has no active cooling requirements, enabling slimmer, enclosed or silent designs.

Operating power is further reduced with VIA PowerSaver™ technology that enables the VIA Eden processor to transition between maximum processor speed and the lowest speed of 400MHz, depending on application requirements, within a single clock cycle, which also ensures seamless running of real-time operating systems and ensures no latency issues.

Enhanced Digital Media Performance with the VIA CN700 IGP Chipset

Fully compatible with all leading operating systems, the new VIA Eden processor based on the advanced 90nm SOI manufacturing process boas ts a host of performance features within the VIA StepAhead™ Technology Suite, including sixteen pipeline stages, support for SSE2 and the advanced SSE3 multimedia 3D instruction sets, a full-speed Floating Point Unit (FPU) and an efficiency-enhanced 128KB full-speed exclusive L2 cache with 32-way associativity for memory optimization. The unique TwinTurbo™ PLL implementation enabled by VIA PowerSaver™ technology acts like an automatic transmission, permitting smooth transition between the maximum and minimum power states within one clock cycle, ensuring always-on service and minimizing latency.

When coupled with the VIA CN700 digital media IGP chipset that supports the new VIA V4 bus that heralds a new era of advanced bandwidth connectivity, the VIA Eden processor delivers exceptional performance for all the most critical entertainment, data streaming, Internet and productivity applications, including smooth digital MPEG-2 video playback, MP3 audio playback, Voice over IP and video conferencing applications, multimedia slideshows and web browsing.

Together with the VIA Eden processor, the VIA CN700 chipset provides the industry leading, low power digital home and business platform through additional support for up to 2GB of high bandwidth DDR2 533 or DDR400 memory, USB 2.0, TV-out as well as support for HDTV up to 1080p resolution, VIA Vinyl Audio 6-channel surround sound , as well as a high speed V-Link interface for a 533MB/sec to feature packed VIA South Bridge options and integrated networking that is highly suited to cool, quiet and low profile digital media or communication devices.

World’s Fastest x86 Security Engine

To address the growing need among corporate, government, and home users to protect sensitive data on their connected devices, VIA has pioneered a holistic approach to computing security by integrating a remarkable suite of security technologies directly onto the processor die, and providing key software tools to enable them.

the VIA Eden processor family based on the 90nm ‘Esther’ core incorporates the world’s most comprehensive security features within the VIA PadLock Security Engine¹. In addition to the world’s best random number generator (RNG) and AES Encryption Engine integrated into the previous processor generation, the VIA PadLock Security Engine in the VIA Eden processor adds SHA-1 and SHA-256 hashing for secure message digests, and a hardware based Montgomery Multiplier supporting key sizes up to 32K in length to accelerate public key cryptography, such as RSA™. The VIA Eden also provides NX Execute Protection, providing protection from malicious software such as worms and viruses, and is used in Microsoft® Windows® XP with SP2. Integrating security directly onto the processor die ensures speeds and efficiency many times that available in software, yet with negligible impact on processor performance.

Security applications that leverage the military-grade capabilities of the VIA PadLock Security Engine can be deployed quickly and easily across a broad range of devices including PCs, thin clients, set top boxes, home digital entertainment centers, point of sale terminals, and intelligent network routers in a wide variety of wired and wireless networking environments.
