    摘要: A method configures a plurality of circuit elements for execution of an application in a first configuration. The method monitors the execution of the application on the plurality of circuit elements to produce monitoring information, using a computerized device, and stores the monitoring information in a storage structure. The method selectively communicates the monitoring information to an external element separate from the computerized device. The external element transforms the first configuration into a second configuration based on the monitoring information. The computerized device receives the second configuration from the external element and reconfigures the plurality of elements into the second configuration.

    摘要: Disclosed are embodiments of on-chip identification circuitry. In one embodiment, pairs of conductors (e.g., metal pads, vias, lines) are formed within one or more metallization layers. The distance between the conductors in each pair is predetermined so that, given known across chip line variations, there is a random chance (i.e., an approximately 50/50 chance) of a short. In another embodiment different masks form first conductors (e.g., metal lines separated by varying distances and having different widths) and second conductors (e.g., metal vias separated by varying distances and having equal widths). The first and second conductors alternate across the chip. Due to the different separation distances and widths of the first conductors, the different separation distances of the second conductors and, random mask alignment variations, each first conductor can short to up to two second conductors. In each embodiment the resulting pattern of shorts and opens, can be used as an on-chip identifier or private key.

    摘要: An apparatus for monitoring the temperature of an integrated circuit device includes a conductive wiring pattern formed on the integrated circuit device, extending into areas of the device to be monitored. A deterministic signal source is configured to generate a deterministic signal along the conductive wiring pattern, with one or more return paths tapped from selected locations along the pattern. A temperature change determination circuit is coupled to the one or more return paths and to a reference signal taken from the deterministic signal source. The circuit is configured to determine a delay between the reference signal and a delay signal traveling through at least a portion of the wiring pattern and a corresponding one of the return paths.

    摘要: A structure and associated method to control a flow of data on a semiconductor device. A transmitter, receiver and transmission line are formed within the semiconductor device. The transmitter, receiver, and transmission line are adapted to control data transfer between a first core and a second core within the semiconductor device. The transmitter is adapted to send a signal over the transmission line to the receiver adapted to receive the signal. The receiver is further adapted to create an impedance mismatch to indicate that the second core is unable to transfer the data. The transmitter is adapted to detect the impedance mismatch.
