Today’s embedded computing applications are far more sophisticated than those of the recent past. Industries such as medical imaging, homeland security, and military defense call for rackmount systems that can run a growing number of complex software applications. In many of these industries the reliable and timely processing of information can mean the difference between life and death. These industries also require equipment that can squeeze into tightly constrained spaces and—in some cases—meet low weight requirements. Providing the needed compute capability inside this space and weight envelope is a considerable challenge.
