PICMG: ratification of COM0 R.3 for COM Express for server grade performance
PICMG released a high-performance revision that adds server-grade functionality to COM Express embedded computing systems. COM Express is widely used in Industrial Automation, Military/Aerospace, Gaming, Medical, Transportation, IoT, and other applications.
Revision 3.0 of COM Express provides for a new Type 7 connector and the addition of up to four 10 Gigabit Ethernet (10GbE) interfaces on the board. Previous revisions of the specification were limited to a single Gigabit Ethernet interface. The higher speed ports open up new markets such as data centers where the high compute density of COM Express can result in increased rack utilization. The 10GbE ports are also ideal for high bandwidth video applications such as surveillance. Another change to the specification includes increasing the number of PCI Express lanes to 32 across the Type 7 connector. This provides a wealth of connectivity and interface options including the ability to facilitate the use of GPGPUs.
