Patent number: 7937594Abstract: A digital logic circuit comprises a programmable logic device and a programmable security circuit. The programmable security circuit stores a set of authorized configuration security keys. The programmable security circuit compares the authorized configuration security keys with an incoming configuration request, and selectively enables a new configuration for the programmable logic device in response to the configuration request. In another exemplary embodiment, a programmable security circuit also stores a set of authorized operation security keys. The programmable security circuit compares the authorized operation security keys with an incoming operation request from the programmable logic device, and selectively enables an operation within the programmable logic device in response to the operation request.Type: GrantFiled: May 16, 2006Date of Patent: May 3, 2011Assignee: Infineon Technologies AGInventors: Stephen L. Wasson, David K. Varn, John D. Ralston

Patent number: 7880497Abstract: The exemplary embodiments provide a resilient integrated circuit. An exemplary IC comprises a plurality of composite circuit elements, a state machine element (SME), and a plurality of communication elements. Each composite circuit element comprises an element interface and a selected circuit element which may vary by element type, and which may be configurable. The state machine element assigns various functions based on element type, such as assigning a first configuration to a first element type, assigning a second configuration to a second element type, and providing a first data link for the corresponding assignments. In response to detection of a fault or failure, the state machine element re-assigns the first configuration to another composite circuit element and creates a second data link for performance of the same function.Type: GrantFiled: May 8, 2009Date of Patent: February 1, 2011Assignee: Element CXI, LLCInventors: Steven Hennick Kelem, Jaime C. Cummins, John L. Watson, Robert Plunkett, Stephen L. Wasson, Brian A. Box, Enno Wein, Charles A. Furciniti, Christopher E. Phillips
