COM Express is a computer on module (COM) that can be used in the same manner as integrated circuits. Each module has its own integrated memory and core CPU functionality, as well as Ethernet, audio, graphics, USB and PC/ST. There are a pair of low profile, high density connectors on the module's bottom side that map all I/O signals. Many of today's most innovative embedded applications can benefit from compact form factors. Older methods of providing these (AGP and PCI-X), can't satisfy top end applications. Those vary from advertising terminals, retail POS, and industrial automation to gaming, medical imaging and more.
COM modules contain all the components of a bootable computer in one easy to find component. Customization and expansion can be implemented on carrier boards specific to the application, and with the COM, those boards offer the same functionality as an entire small computer. The COM Express specification is an open COM standard, offering modular building blocks to create a solution for just about any application, and enabling smooth transitions from older interfaces like AGP and PCI, to newer ones, including SATA, PCI Express, and SDVO.
These rugged products first started appearing in 2005. They offer different embedded applications, especially in form factors where add-in cards aren't able to be used. COM methodology gives embedded developers a faster time to market, reduced risk and cost of development, better control over form, fit and function, and a lower total cost of ownership to the consumer, via scalability. That means it could be used with some big advances in embedded technology out there, freeing R&D from dealing with changing processors and other problems.
A key reason embedded developers prefer the COM Express methodology is that it lets them focus available engineering resources to meet their business requirements. They don't have to spend them on figuring out how to implement evolving I/O technologies or new generations of processors. Since the embedded world is probe to volatile fluctuations in demand and serious competition, the COM approach lets system manufactures respond effectively. They can modify existing designs and expand product portfolios a lot more easily. Embedded products that have five to ten year life cycles benefit particularly from this, since their I/O capabilities and performance have to be constantly kept up to date.
Com Express helped accelerate development in some of the most dynamic application segments on the market today. Whether it includes advertising and retail applications, real-time medical imaging, testing equipment, hospitality, gaming, or entertainment, automation for industrial applications, and even security and military applications. COM Express has safeguarded research and development investments and lowered the total cost of ownership in each of these market segments.
