  • Publication number: 20170140073
    Abstract: Technologies are described to automate design of field programmable gate array (FPGA) circuits, specifically for fast and efficient architectures for large integer adders and counters through direct instantiation of carry chain primitives and lookup tables in circuit description. In some examples, placement of circuits on relatively adjacent slices may be controlled such that the slices are strongly and logically coupled to enable compact placement and thereby contributing to reduced routing delay and FPGA chip area. Design descriptions and constraint files may be automatically generated by a design application providing operand-width scalability with respect to operating frequency of the designed circuit.

  • Patent number: 9311323
    Abstract: Technologies are presented for data deduplication that operates at relatively high throughput and with relatively less storage space than conventional techniques. Building upon content-dependent chunking (CDC) using Rabin fingerprints, data may be fingerprinted and stored in variable-size chunks. In some examples, data may be chunked on multiple levels, for example, two levels, variable size large chunks in the first level and fixed-size sub-chunks in the second level, in order to prevent sub-chunks common to two or more data chunks from not being deduplicated. For example, at a first level, a CDC algorithm may be employed to fingerprint and chunk data in content-dependent sizes (variable sizes), and at a second level the CDC chunks may be sliced into small fixed-size chunks. The sliced CDC chunks may then be used for deduplication.

  • Patent number: 9184959
    Abstract: A method of increasing a performance of a super-regenerative receiver (SRR), includes initializing a quench rate to be greater than or equal to 2 based on a parameter, and comparing a decision metric to a lower threshold value, the decision metric established from a first receiver operating characteristic (ROC). The method further includes estimating a phase offset, using an over-quench method, and aligning quench signals at the quench rate of 1, and comparing the decision metric to a higher threshold value to minimize a false alarm probability. The method further includes confirming packet detection and the phase offset, using the over-quench method.

  • Patent number: 9163255
    Abstract: Polynucleotides isolated from chickpea are disclosed herein. The disclosed polynucleotides of the present invention provide genotype-dependent spatial information on the presence and relative abundance of each gene. The transcriptomic analysis of the polynucleotides revealed (649) non-cannonical genes besides many unexpected candidates with known biochemical functions, which have never been associated with pathostress-responsive transcriptome. The polynucleotides disclosed in the present invention can be used as a molecular tool for isolation of novel genes from plants that can be used for plant improvement. Further, the polynucleotide responsible for improving immunity against fungal pathogen in plants is disclosed herein. The present invention also provides a method of improving immunity against fungal pathogen in plants. Transgenic plants exhibiting improved immunity against fungal pathogen are also provided in the present invention.
