摘要： A method for electronically fused encryption key security includes inserting a plurality of inverters between a bank of security fuses and a fuse sense logic module. The method also includes sensing an activated set of the bank of security fuses and the plurality of inverters. The method further includes comparing the sensed activated set of the bank of security fuses and the plurality of inverters with a software key to determine whether at least a substantial match is made.

摘要： An approach for power supply noise mitigation on a processor is provided. In one aspect, the approach comprises a central computing unit operatively coupled to the processor to execute program operations. The approach further comprises a calibration circuit adapted to determine a first threshold on the processor to be used for comparison performed dynamically through the use of a detection circuit. A detection circuit adapted to dynamically monitor system operation of the processor and indicate if the first threshold is violated and a counting circuit adapted to prevent voltage from drooping if one or more voltage sensing measurements violates the first threshold are also provided.

摘要： A first of a plurality of data lanes of a first of a plurality of processor links is determined to have a weakest of base performance measurements for the plurality of data lanes. A switching data pattern is transmitted via a first set of the remainder processor links and a quiet data pattern is transmitted via a second set of the remainder processor links. If performance of the first data lane increases vis-à-vis the corresponding base performance measurement, the first set of remainder processor links is eliminated from the remainder processor links. If performance of the first data lanes decreases vis-à-vis the corresponding base performance measurement, the second set of remainder processor links is eliminated from the remainder processor links. The above operations are repeatedly executed until an aggressor processor link that is determined to decrease performance of the first of the plurality of data lanes is identified.

摘要： A method, system, and computer-usable medium for implementing a programmable DMA master with data checking utilizing a drone system controller. According to an embodiment of the present invention, a drone processor generates a collection of random data and stores a first and second copy of the collection of random data in a first and second memory location in a drone memory. The drone processor writes a third copy of the collection of random data in a processor memory. When the drone processor retrieves the third copy from the processor memory, the drone processor writes the third copy in the second memory location in the drone memory. When the drone processor compares the first copy with the third copy, the results of the compare is written in a status location within the drone processor.

摘要： A processor link that couples a first processor and a second processor is selected for validation and a plurality of communication parameter settings associated with the first and the second processors is identified. The first and the second processors are successively configured with each of the communication parameter settings. One or more test data pattern(s) are provided from the first processor to the second processor in accordance with the communication parameter setting. Performance measurements associated with the selected processor link and with the communication parameter setting are determined based, at least in part, on the test data pattern as received at the second processor. One of the communication parameter settings that is associated with the highest performance measurements is selected. The selected communication parameter setting is applied to the first and the second processors for subsequent communication between the first and the second processors via the processor link.
