You can easily customize the cpuModule by stacking PCI-104, PCI/104-Express, or PCIe/104 modules such
as video controllers, Digital Signal Processors, drive carriers, 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 BIOS. Drivers in the BIOS allow booting from hard disk, or UEFI
shell, thus enabling the system to be used with traditional disk drives or nonmechanical drives. Booting to
USB devices is also supported.
The cpuModule and BIOS are compatible with any real-time operating systems for PC compatible
computers, although these may require creation of custom drivers to use the aDIO and watchdog timer.
aDIO
RTD’s exclusive aDIO™ is 12 digital bits configured as 8 bit-direction programmable and 4-bit
port-direction programmable I/O, plus 2 strobe inputs giving you any combination of inputs and outputs.
Match, event, and strobe interrupt modes mean no more wasting valuable processor time polling digital
inputs. Interrupts are generated when the 8 bit-direction programmable digital inputs match a pattern or on
any value change event. Bit masking allows selecting any subgroup of eight bits. The strobe input latches
data into the bit-programmable port and generates an interrupt.
