Direct Media Interface (DMI)
ThereisaDirectMediaInterfaceGen2(DMI2)4xlinkbetweenthePCHandCPU0thatis
capableofPCIExpressGen2transferrates(5Gb/s)foratheoreticalbandwidthof20Gb/sin
eachdirection.ThislinkisusedtopassI/OfromtheSATA,SAS,LPC,andUSBperipheralsto
theCPUormemory,alongwithinterruptsandSMI,SCI,andSERRnotification.
Universal Serial Bus (USB)
ThePCHcontainstwoEnhancedControllerHostInterface(EHCI)controllers,providingupto
fourteenUSB2.0ports.Eachportallowsdatatransfersupto480Mb/s.OntheCPM,the
followingUSBportsareprovided:
