  • Publication number: 20170046281
    Abstract: Encryption of data within a memory is provided by key generation circuitry which serves to generate a key as a function of the address within the memory being accessed and then encryption circuitry or decryption circuitry which serve respectively to encrypt or decrypt the data as a function of the key that has been generated based upon the address. The encryption and the decryption may be performed using a bitwise XOR operation. The key generation circuitry may have the form of physically unclonable function circuitry, which varies from instance to instance of implementation and that operates to generate the same key for the same address upon both write and read operations within the same instance.

  • Patent number: 9529671
    Abstract: An apparatus has a plurality of storage units. A parity generator is configured to generate a parity value in dependence on the respective values stored in the plurality of storage units. The parity generator is configured such that determination of the parity value is independent of a read access to the data stored the plurality of storage units. A detector is configured to detect a change in value of the parity value.

  • Patent number: 9454260
    Abstract: Embodiments of the present invention disclose a system and method for enabling multi-display input. According to one embodiment, the presence of an object is detected within a display area of a first display panel or a second display panel via at least one optical sensor coupled to a processor. Positional data of the object is received from the optical sensor, and a control operation associated with either the first display or second display panel is determined based on the positional data received from the optical sensor.

  • Patent number: 9449717
    Abstract: A data processing apparatus has at least one memory and processing circuitry. A memory built-in self-test (MBIST) interface receives a MBIST request indicating that a test procedure is to be performed for testing at least one target memory location. Control circuitry detects the MBIST request and reserves for testing at least one reserved memory location including the target memory location. During the test procedure, the memory continues servicing memory transactions issued by the processing circuitry that target a memory location other than the reserved location reserved by the control circuitry. The processing circuitry is stalled if it attempts to access a reserved memory location. Testing consists of short bursts of transactions which occur infrequently. In this way, MBIST testing may continue while the processor is operation in the field with reduced performance impact.

  • Publication number: 20160223479
    Abstract: A system for measuring the thermal diffusivity of a material includes a housing having an upper portion and a lower portion, a plate holding the material in a fixed position between the upper portion and lower portion of the housing, and a source at the lower portion of the housing projecting heat onto the material along a first axis that is perpendicular to the plate. A sensor at the lower portion of the housing is movable in relation to the plate and senses the heat radiating through the material along a second axis that is perpendicular to the plate and offset from the first axis. A controller receives data from the sensor and calculates the thermal diffusivity of the material.
