  • Patent number: 11403447
    Abstract: Rebuilding a next compile-time Intellectual Property (IP) core can include determining an IP core included in a runtime design for an integrated circuit (IC) by evaluating metadata of the runtime design. The IP core specifies a circuit configured for implementation in programmable circuitry of the IC. Source code for the IP core may be retrieved automatically based on source data read from the metadata. A new instance of the IP core, including the source code, may be generated in a memory. The new instance of the IP core may be included within a new compile time design.

  • Publication number: 20200237314
    Abstract: A computer implemented method and system for detecting premature ventricular contractions (PVCs) are provided. The method is under control of one or more processors configured with specific executable instructions. The method obtains a cycle length (CL) distribution metric that plots a series of cardiac beats into one of a set of transition types based on R-R interval (RRI) difference pairs associated with the cardiac beats. The CL distribution metric plots the cardiac beats based on a comparison between combinations of the RRI difference pairs for corresponding combinations of the cardiac beats. The method calculates a distribution characteristic for the cardiac beats, from the series of cardiac beats that exhibit a first transition type from the set of transition types and calculates a discrimination score based on the distribution characteristic of the cardiac beats across the CL distribution metric.

  • Patent number: 10613875
    Abstract: A system includes a runtime generator implemented in programmable circuitry of an integrated circuit, wherein the runtime generator is parameterizable at runtime of the integrated circuit to perform at least one of detecting a symbol pattern within a data stream or generating pseudo random number binary sequences. The system can include a processor configured to execute program code, wherein the processor is configured to provide first parameterization data to the runtime generator. In response to receiving the first parameterization data from the processor at runtime of the integrated circuit, the runtime generator implements a first automaton circuit configured to perform the at least one of the detecting the symbol pattern or the generating the pseudo random number binary sequences.

  • Patent number: 10474610
    Abstract: An integrated circuit can include programmable circuitry configured to implement an overlay circuit specified by an overlay. The overlay circuit can include a trace buffer configured to receive a probed signal from circuitry within the overlay circuit. The trace buffer can be configured to generate trace data from the probed signal and store the trace data in a runtime allocated memory. The integrated circuit also can include a processor coupled to the programmable circuitry and configured to control operation of the trace buffer. The processor can be configured to read the trace data from the runtime allocated memory.

  • Patent number: 10289093
    Abstract: A system can include a finite state machine generator implemented in programmable circuitry of an integrated circuit. The finite state machine generator is parameterizable to implement different finite state machines at runtime of the integrated circuit. The system can include a processor configured to execute program code. The processor is configured to provide first parameterization data to the finite state machine generator at runtime of the integrated circuit. The first parameterization data specifies a first finite state machine and the finite state machine generator implements the first finite state machine in response to receiving the first parameterization data from the processor.

  • Patent number: 7991185
    Abstract: Embodiments of the invention are a novel splicing detection scheme that detects the spliced images by distinguishing image features that are extracted by exploiting both magnitude and phase information of a given image. The image features include the statistical moments of characteristic functions of wavelet subbands of a test image and a prediction-error image. In addition, the approximation (LL) subband at different levels is individually erased by forcing the wavelet coefficients to zero and the inverse wavelet transform is applied in order to produce reconstructed image with enhanced high frequency components. Further, the moments of the characteristic functions of these reconstructed images provide additional image features. Moreover, the statistics (mean, variance, skewness and kurtosis) of 2-D phase congruency array associated with the reconstructed images provide additional image features for splicing detection.

  • Patent number: 7940989
    Abstract: A method and apparatus for a novel statistical model based on Benford's law for the probability distributions of the first digits of the block-DCT and quantized JPEG coefficients. A parametric logarithmic law, the generalized Benford's law, is formulated. Furthermore, some potential applications of this model in image forensics, which include the detection of JPEG compression for images in bitmap format, the estimation of JPEG compression Q-factor for JPEG compressed bitmap image, and the detection of double compressed JPEG image. Experimental results demonstrate the effectiveness of the statistical model used in embodiments of the invention.

  • Publication number: 20090023629
    Abstract: The present invention relates to compositions comprising polycation-complexed protein crystals and hyaluronic acid. Advantageously, the compositions of this invention are stable, long-acting and avoid local reactions at the injection site. Compositions according to this invention include sustained-release human growth hormone compositions. Such compositions are useful for treating a subject having a disorder associated with human growth hormone deficiency or that is ameliorated by human growth hormone therapy.
