The company supports and provides drivers for Microsoft Windows 7, 8 , and Embedded Compact, as well as Linux based operating systems. A user’s guide can be downloaded for each type of board (Qseven or COM Express). Several starter kits and evaluation kits are also available both for Qseven ad COM Express modules such as conga-SBM3/Qseven mobility starter kit, and contga-TEVAL evaluation carrier board for COM Express Type 6 modules.
The block diagram above now looks like very much like an ARM based CoM, as Intel Bay Trail “processors” are “SoCs” integrating the CPU cores, GPU with OpenGL 3.0, OpenGLES 2.0, DirectX 11, OpenCL 1.2, hardware video codec, as well as the chipset for I/O interfaces. There are still some differences as Ethernet is done via a GbE to PCIe chip which is rarely seen with ARM SoCs as Ethernet is usually built-in, and I can’t remember having ever seen an LPC bus in ARM SoCs, nor a “board controller”, except if we consider the PMIC (Power Management IC) to be a board controller.
More information is available on Congatec conga-QA3 and conga-TCA3 pages, and the company will showcase their new modules and kits at Embedded World in Nuremberg, Hall 1, Stand 358. You may also want to watch the introduction video below.
