  • Patent number: 10114649
    Abstract: An instruction control interface is provided for automatically controlling assigning of one or more instructions for processing by one or more processor cores of a computing device. The control interface separately monitors temperatures of multiple logic units within each processor core of the processor core(s) of the computing device, and controls assigning of one or more instructions for processing by a particular processor core(s) based, at least in part, on the separately monitored temperatures of the multiple logic units within the processor core(s).

  • Patent number: 9971861
    Abstract: Aspects include techniques for selective boundary overlay insertion for hierarchical circuit design. A method may include determining, by a processing device, a block type of a child block. The method may further include electively inserting, by the processing device, at least one of an instantiated boundary overlay and a merged boundary overlay into the hierarchical circuit design based on the block type of the child block. The instantiated boundary overlay enables a parent block to pass a testing at an out-of-context level, and the merged boundary overlay enables the parent block to continue to pass the testing when the child block is inserted into the parent block associated with the child block.

  • Patent number: 9728274
    Abstract: A technique is provided for system reliability. An input is received, and a computation operation on the input is repeated to generate multiple output values. The multiple output values are stored in a table along with a number of hits for each distinct output value in the multiple output values, and the number of hits indicates a number of times each distinct output value was generated by the repeating. A reliability circuit checks whether the number of hits for any one distinct output value meets a confidence threshold. Based on meeting the confidence threshold for the number of hits, the any one distinct output value is output. Based on the number of hits for the any one distinct output value not meeting the confidence threshold, the computation operation is continuously repeated on the input until the number of hits for the any one distinct output value meets the confidence threshold.

  • Patent number: 9626220
    Abstract: A multiple processor core computer system interface assigns instructions to partially functional processor cores based on processing resources available in each partially functional core. Each processor core is labeled as fully functional, partially functional, or non-functional, and an indicator is provided for each partially functional processor core that shows what processing resources are available for a respective core. The indicators can be stored in memory after final test. The interface can monitor cores for changes in available resources and update respective indicators, such as by superseding an existing indicator with or creating a new indicator in read-write memory.

  • Patent number: 9043683
    Abstract: A method for providing error detection and/or correction to an array of storage cells includes determining a sensitive direction and an insensitive direction of the storage cells and adding a first error control mechanism to the array of storage cells in the insensitive direction.
