Direct Media Interface (DMI)

Note:The DMI interface is only present in 2-Chip platform processors.

Direct Media Interface (DMI) connects the processor and the PCH.

The main characteristics are as follows:

  • 8 lanes Gen 4 DMI support

  • 4 lanes Gen 4 Reduced DMI support

  • 16 GT/s point-to-point DMI interface to PCH

  • DC coupling - no capacitors between the processor and the PCH

  • PCH end-to-end lane reversal across the link

  • L0 (Active) and L1 (Low power) states support

  • Half-Swing support (low-power/low-voltage)
