Intel® Direct Connect Interface (DCI)

Intel® Direct Connect Interface (DCI) is an Intel® tool transport technology that allows connection between the host system running a debug, validation or test tool stack and a closed chassis debug through of USB 3.1 Gen2 and USB 2.0 Host ports out from Intel® processor. Intel® DCI requires embedded in the silicon to “bridge” the gap between standard I/O ports and the debug interfaces including JTAG, probe mode, hooks, trace infrastructure etc. To control the operation of this embedded logic, Intel® DCI packet based protocol is invented to allow controls and data can be sent or received. This protocol can operate over a few different physical transport paths to the target which known as “hosting interfaces”.

Note:Further information on how to run Intel® DCI through Intel® System Studio System software is available at, https://software.intel.com/en-us/articles/system-debugging-via-direct-connect-interfacedci-of-intel-system-debug.
