Vega86 Overview

The Vega86 Single-Board-Computer series (powered by VIA Mark CoreFusion processor) offers high performance, cost-effective and energy efficient processor with integrated ProSavage4 SA graphics controller.

The complete board consists of the Mark CoreFusion processor and the VT82C686B PCI-ISA South Bridge, Realtek RTL8100B 10/100 Fast Ethernet Controller,etc. The processor integrates VIA's high-performance ProSavage4 3D / 2D graphics controller, LCD and Flat Panel display interfaces, with further superior performance between the CPU, DRAM and PCI bus with pipelined, burst, and concurrent operation. The South Bridge is PC98 / PC99 compliant with integrated UltraDMA-66 / 33 IDE, 2 (or 3) USB (1.1) ports, a complete power management feature set, Super-I/O functions (floppy disk drive interface and serial / parallel ports), and AC-97 link supporting digital audio functions.

Overview of Vega86 Single-Board-Computer Board

Providing 533MHz CPU speed grade, the Vega86 SBC is also equipped with a deep In-Order Queue and SSE instructions support, which is suitable to enhance video, audio and faster 3D graphics performance.

The Vega86 SBC supports DRAMs up to 256MB. As to the DRAM controller, it meets the standard PC133 Synchronous DRAM (SDRAM). The Synchronous DRAM interface allows zero wait state bursting between the DRAM and the data buffers at 133MHz.

The Vega86 SBC integrates S3 Graphics and 128-bit ProSavage4 graphics accelerators that bring mainstream graphics performance to the Value PC with leading-edge 2D, 3D and DVD video acceleration into a cost effective package. Vega86 SBC also combines the industry's first integrated AGP 4X solution with Microsoft Direct-X texture compression and massive 2Kx2K textures to deliver unprecedented 3D performance and image quality for the Value PC mobile market.

Vega86 SBC's South Bridge supports four levels (doubleword) of line buffers, type F DMA transfers and delay transaction to allow efficient PCI bus utilization and (PCI-2.2 compliant). The VT82C686B also includes an integrated Super I/O, integrated DS12885 style real time clock with extended 256 byte CMOS RAM, integrated master mode enhanced IDE controller with full scatter / gather capability, integrated two (or three) USB (1.1) interface with root hub and two function ports with built-in physical layer transceivers, Distributed DMA support, integrated AC-97 link for basic audio functions and integrated OnNow / ACPI compliant advanced configuration.

Regarding the network architecture application, Vega86 SBC equips with the Realtek RTL8100B, which is a highly integrated, cost-effective single-chip Fast Ethernet controller able to provide 32-bit performance, PCI bus master capability, and full compliance with IEEE 802.3u 10/100Base-T specifications and IEEE 802.3x Full Duplex Flow Control.
