| CM-i686 (686CORE) 模块 |
| |
The CM-i686 module is a tiny single board computer, designed to
serve as a building block in embedded applications. The CM-i686 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.
The CM-i686 is both small and inexpensive. Its small size allows
integration into hand-held and mobile applications, providing a
powerful computing core. Its extremely low price makes it an ideal
selection for cost-sensitive applications. Based on National Semiconductor's
GeodeTM architecture, the CM-i686 provides excellent price/functions/performance
in comparison with any other PC-compatible embedded system.
The feature set of the CM-i686 module combines a 64-bit CPU/memory
architecture, Flash Disk and essential computing peripherals. For
embedded applications, the 686CORE 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-i686 includes ready-to-run packages for:
- Linux
- Windows CE
- Windows 9x / NT / XP
- VxWorks
- DOS
