Block Diagram
The next figure shows a simplified block diagram of the CMX158886 cpuModule.
Figure 2 CMX158886 cpuModule Simplified Block Diagram
You can easily customize the cpuModule by stacking PCI-104 modules such as video controllers, modems, LAN
controllers, or analog and digital data acquisition modules. Stacking modules onto the cpuModule avoids
expensive installations of backplanes and card cages, and preserves the module's compactness.
The cpuModule uses the RTD Enhanced AMI BIOS. Drivers in the BIOS allow booting from floppy disk, hard disk,
ATA/IDE Disk Chip, or boot block flash, thus enabling the system to be used with traditional disk drives or
nonmechanical drives. Boot from USB devices and network are also supported.
The cpuModule and BIOS are also compatible with most real-time operating systems for PC compatible
computers, although these may require creation of custom drivers to use the aDIO and watchdog timer.
