EUS FS - Alice II - Embeddable Single Board Computer

Description

EUS FS is an "open" system board designed for industrial control and data acquisition applications. It is equipped with a 32-bit CPU working @ 200MHz (Etrax FS), Xilinx's gate array (Spartan 3E) and support electronics. A BSP package contains Linux operating system version 2.6, driver for communication with FPGA and peripheral devices. Example FPGA cores are available in source form, along with full board documentation and schematics.
