The EXC-8000ccXMC is part of Excalibur’s 8000 family of multiprotocol boards. This conduction cooled XMC interface board has a PCI Express host interface and supports up to 4 Px modules, 2 RTx 5 channel modules, 1 Discrete and 1 Serial module. Due to the constraints of the XMC specification the modules are integrated onto the board itself rather than as physically separate modules. 
The EXC-8000ccXMC supports Direct Memory Access (DMA), which enables the board to access system memory for reading and writing independently of the computer’s CPU. This results in faster data transfer to and from modules that support DMA, with much less CPU overhead than when not using DMA.
The EXC-8000ccXMC is supplied with C drivers, including source code.
