Desktop Expansion Reaches the Consumer Market

Slots, slots, and more slots has long been the cry of industrial and commercial users since the advent of the PC. Slots provide the ability to add specialized cards that perform application functions that the PC or Mac  Workstation don’t have. In fact, the Mac Pro Workstation only provides one PCIex16 and two PCIe x4 Gen2 slots. Laptops offer even a greater challenge if you want to add application boards because they don’t provide any extra slots.

PCIe over Cable Goes Mainstream

In 2007 the PCI-SIG approved the PCI Express External Cabling Specification that defines how PCI Express can be implemented over a standard cable. This new capability allows the full bandwidth of the PCIe bus to be utilized within multiple chassis systems and small local networks.

PCIe Outside the Box

Now that PCI Express has achieved nearly 100% acceptance in desktop and laptop PCs, designers are looking to leverage the technology into other form factors and applications.  Over 60 form factors have now been defined using PCIe as the backplane bus architecture.
