1.5.1

Direct Media Interface (DMI)

Direct Media Interface (DMI) is the chip-to-chip connection between the processor and
PCH. This high-speed interface integrates advanced priority-based servicing allowing
for concurrent traffic and true isochronous transfer capabilities.
1.5.2

Display Interfaces

Display is divided between the processor and the PCH. The processor houses the
memory interface, display planes, and pipes while the PCH has transcoder and display
interface or ports. The PCH receives the display data over Intel
®
Interface (Intel
and sends the data through the display interface.
®
1.5.2.1 Intel
Intel FDI connects the display engine in the processor with the display interfaces on
the PCH. The display data from the frame buffer is processed in the display engine of
the processor and sent to the PCH over the Intel FDI where it is transcoded as per the
display protocol and driven to the display monitor.
1.5.2.2 High-bandwidth Digital Content Protection (HDCP)
HDCP is the technology for protecting high definition content against unauthorized
copy or unreceptive between a source (computer, digital set top boxes, etc.) and the
sink (panels, monitor, and TVs). The PCH supports HDCP 1.4 for content protection
over wired displays (HDMI).
