The CM-i686B
module is a tiny
single board computer, designed to serve as the heart of SB-i686 PC/104+
board. The CM-i686B module has all the components needed to run operating
systems such as Windows, Linux or VxWorks. Ready packages for these
operating systems are available from
CompuLab. Based on AMD's GeodeTM architecture, the
CM-i686B provides excellent price / functions / performance ratios in comparison with any
other PC-compatible embedded system.
The feature set of the CM-i686B module combines a
64-bit memory architecture, Flash Disk and essential computing peripherals. For embedded
applications, the CM-i686B provides a 32-bit PCI bus, 100Mbit Ethernet,
serial ports, general purpose I/O lines and many
other essential functions.
Software support for
the CM-i686B includes ready-to-run packages for:
* Linux
* Windows CE, XP
* VxWorks
* DOS
