Taipei, Taiwan VIA Technologies, Inc. has launched its new fanless VIA Eden processor family with the VIA V4 bus. Included is the ultra low voltage VIA Eden ULV processors housed in the compact nanoBGA2 package that measures 21mm x 21mm.
Based on the VIA CoolStream, the 1GHz VIA Eden ULV processor has the low maximum design power (TDP) of just 3.5 watts and its power of just 7.5 watts. The whole VIA Eden processor family boasts the industry’s lowest idle power of just half a watt, according to the company.
Specifically targeted at a range of business, industrial and commercial applications such as thin clients, silent desktops, IPCs and set top boxes, the X86-based VIA Eden processor line is available at different speeds to meet the needs of those different vertical market segments. All of the new processors have been designed to operate at very low maximum power (TDP); ranging from 400MHz at just 2.5W up to 1.2GHz at 7W. The ultra low voltage skus, VIA Eden ULV processors, take power-efficiency a quantum step further, with the 1GHz and 1.5GHz parts designed for a maximum of an incredibly low 3.5W and 7.5W respectively.
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.
The new VIA Eden processor boasts competitive write bandwidth and linear ordering modes, as well as MMX, SSE2 and SSE3 support for enhanced multimedia performance, and 128KB of both L1 and L2 on-die cache. It also integrates the world’s most comprehensive set of security tools in the VIA PadLock Security Engine, which can be enabled within applications to provide military-grade protection of business or personal information.
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 to enable slimmer, enclosed or silent designs.
Fully compatible with all leading operating systems, the VIA Eden processor family is available at speeds from 400MHz to 1.5GHz and boasts 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.
Coupled with the VIA CN700 digital media IGP chipset, the VIA Eden processor provides smooth playback of digital video and audio, and offers exceptional memory and peripheral support. The unique TwinTurbo dual-PLL implementation with 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.
The VIA PadLock Security Engine integrated within the VIA Eden processor, provides on-die hardware acceleration for key cryptographic operations and ensures speeds and efficiency many times that available in software, yet with negligible impact on processor performance. In addition to the quantum-based random number generator (RNG) and AES Encryption Engine provided in the previous processor generation, 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 processor also provides execute protection (NX), preventing the proliferation of malicious software such as worms and viruses, and is used in Microsoft Windows XP with SP2.
The new VIA Eden processor line is shipping now. US pricing in 1K units for the 1.5 Ghz Eden ULV is $249. The 1.0 Ghz version is $299.
