SAN JOSE, Calif. -- Taiwan's Via Technologies Inc. has rolled out the first members of its x86-based microprocessor line, build around its previously-announced 64-bit superscalar technology.
Building on its VIA C7 processor family, the new VIA Nano microprocessor line is said to offer as much as four times the performance within the same power range as previous products. There are two lines in the family: the VIA Nano L-series processors for mainstream desktop and mobile PC systems and the U-series for ultra mobile products.
Based on Fujitsu Ltd.'s 65-nm process, the VIA Nano runs up to 1.8-GHz and includes an 800-MHz bus. The Nano supports a 64-bit instruction set and branch prediction for processor efficiency and performance. The superscalar, speculative and out-of-order architecture was recently announced by Taipei-based Via.
The processors also support a floating point unit, a security engine, new SSE instructions, two 64-KB L1 caches and a 1-MB exclusive L2 cache with 16-way associativity. The processors are housed in compact 21- x 21-mm nanoBGA2 packages, which are said to support an idle power mode as low as 100mW (0.1W).
There are five processors in the family. The VIA Nano L2100 processor runs at 1.8-GHz and has a power consumption of 25 Watts. The VIA Nano L2200 processor runs at 1.6-GHz and has a power consumption of 17 Watts.
The VIA Nano U2400 processor runs at 1.3-GHz or more at 8 Watts. The VIA Nano U2500 processor operates at 1.2-GHz at 6.8 Watts. And the VIA Nano U2300 processor runs at 1.0-GHz at 5 Watts.
"VIA Nano processors represent the next generation of x86 technology, providing the fundamental building blocks for a new genre of optimized computing solutions," said Wenchi Chen, president and CEO of Via, in a statement. Via also sells chipset for PC applications.
