The **Unified Media Interface** (**UMI**) interconnect is the link between an [AMD Accelerated Processing Unit](/source/AMD_Accelerated_Processing_Unit) (APU) and the [FCH (Fusion Controller Hub)](/source/Comparison_of_AMD_chipsets#Fusion_controller_hubs_.28FCH.29).[1][2] It is similar to [Intel](/source/Intel)'s [DMI](/source/Direct_Media_Interface), and is based on [PCI Express](/source/PCI_Express).[3] The Fusion Controller Hub is similar to the [southbridge](/source/Southbridge_(computing)) of earlier chipsets.
