Optoelectronic modules include a silicon substrate in which or on which there is an optoelectronic device. An optics assembly is disposed over the optoelectronic device, and a spacer separates the silicon substrate from the optics assembly. Methods of fabricating such modules also are described.

Optoelectronic modules having a silicon substrate, and fabrication methods for such modules

The present disclosure describes refresh control methods for generating distance data and optoelectronic modules that are operable to provide distance information at a predetermined refresh rate, but with a reduction in overall power consumption attributable to the distance determinations.

Power savings through refresh control for distance sensing devices

Customer content is securely loaded on a field programmable gate array (FPGA) located on a secure cryptography card. The customer content is loaded such that it may not be extracted. A customer obtains a secure cryptography card that includes a field programmable gate array and a master key generated by the secure cryptography card. The customer loads customer specific content on the field programmable gate array, wherein, based on the loading, the customer specific content is secure from extraction via the master key by at least entities other than the customer.

Customer load of field programmable gate arrays

In one embodiment, a computer-implemented method includes assigning a time budget to each of a plurality of virtual functions in a single-root input/output (SRIOV) environment, where a first time budget of a first virtual function indicates a quantity of cycles on an engine of the SRIOV environment allowed to the first virtual function within a time slice. A plurality of requests issued by the plurality of virtual functions are selected by a computer processor, where the selecting excludes requests issued by virtual functions that have used their associated time budgets of cycles in a current time slice. The selected plurality of requests are delivered to the engine for processing. The time budgets of the virtual functions are reset and a new time slice begins, at the end of the current time slice.

Arbitration in an SRIOV environment

A method for updating code images in a system includes booting a first image of a code with a sub-system processor, receiving a second image of the code, performing a security and reliability check of the second image of the code with the sub-system processor, determining whether the security and reliability check of the second image of the code is successful, storing the second image of the code in a first memory device responsive to determining that the security and reliability check of the second image of the code is successful, designating the second image of the code as an active image, and sending the second image of the code to a second memory device, the second memory device communicatively connected with the first memory device and a main processor.

Code updates in processing systems

Embodiments relate to modular reductions. An aspect includes a system to perform modular reductions. The system includes a shift register to store an input string or number. The system also includes a plurality of processing elements arranged in a pipeline configuration to convert the input string to a predefined alphabet or to convert the number to a different base based on a plurality of modular reductions, an output of one of the plurality of processing elements being an input to a subsequent one of the plurality of processing elements in the pipeline as part of a recursive division, and an input of a first one of the plurality of processing elements in the pipeline being an output of the shift register.

Pipelined modular reduction and division

A method for integrity checking for a cryptographic engine in a computing system includes monitoring a state of a side channel of the cryptographic engine during operation of the cryptographic engine by a side channel monitor; comparing the state of the side channel to a side channel model of the cryptographic engine to determine whether a mismatch exists between the state of the side channel and the side channel model; and based on a mismatch between the state of the side channel and the model of the side channel, indicating an error in the cryptographic engine.

Integrity checking including side channel monitoring

An arrangement for the protection of cryptographic keys and codes from being compromised by external tampering, wherein the arrangement is utilized within a multilayered securing structure. More particularly, there is provided a multilayered securing structure for the protection of cryptographic keys and codes, which may be subject to potential tampering when employed in computers and/or telecommunication systems. A method is provided for producing such multilayered securing structures within a modular substrate with the intent to protect cryptographic keys and codes which are employed in computers and/or telecommunication systems from the dangers of potential tampering or unauthorized access.
