{{intel title|Innovation Engine}}
'''Innovation Engine''' ('''IE''') is a tiny [[microcontroller]] [[coprocessor]] integrated within [[Intel]]'s server chipsets that provides the framework necessary for system designers to create their own highly customized firmware. From an architectural standpoint, IE is very similar to Intel's {{intel|Management Engine}} (ME), but is designed as an "open engine", allowing system designers to develop their own differentiating [[firmware]]. IE complements ME and are both present starting with the introduction of the Lewisburg [[chipset]].

'''Innovation Engine''' ('''IE''') is a tiny [[microcontroller]] [[coprocessor]] integrated within [[Intel]]'s server chipsets that provides the framework necessary for system designers to create their own highly customized firmware. From an architectural standpoint, IE is very similar to Intel's {{intel|Management Engine}} (ME), but is designed as an "open engine", allowing system designers to develop their own differentiating firmware.
 
 
== Overview ==
 
Intel introduced Innovation Engine (IE) starting with the {{intel|Lewisburg|l=chipset}} [[chipset]] (i.e., {{intel|Skylake-SP|l=core}} parts). IE is integrated along with {{intel|Management Engine|ME}} into the chipset. Whereas ME is designed specifically for Intel's features, IE is designed specifically for system designers. That is, Intel only provides the hardware to operate IE but unless the system designers develop specific firmware for it, it does not do anything.

Like Intel's ME, IE runs on a {{arch|32}} [[x86]] {{intel|Quark}} microcontroller. IE runs cryptographically signed "IE code" only, bound to the system-builder. Unauthenticated code will not load. Unlike ME, IE has additional access to UART. There is also an optional baseboard management controller (BMC) access for system designers that implement IE firmware features that communicates directly with the network.
