Southbridge Agnostic Design

XI3 is the only architecture to offer a "Southbridge Agnostic" design. By placing the Southbridge chip (the chip that controls all of the logic or I/O interfaces) on a separate board than the Northbridge, Xi3 allows an infinite amount of functions to be easily integrated into one core design.
Ninety percent of the development headaches, testing and design efforts are typically focused on redundant parts of the system. For example, every computer or computing device needs some type of processor, memory, and video memory. What differentiates special application computers from off the shelf systems is the integration of specialty Southbridge and other logic chips. Xi3 allows these specialty chips to be easily integrated into the "core" design without the headaches and risk of designing an entire single-plane motherboard from scratch.
