  • Publication number: 20230153615
    Abstract: The technology of this application relates to a neural network distillation method, applied to the field of artificial intelligence, and includes processing to-be-processed data by using a first neural network and a second neural network to obtain a first target output and a second target output, where the first target output is obtained by performing kernel function-based transformation on an output of the first neural network layer, and the second target output is obtained by performing kernel function-based transformation on an output of the second neural network layer. The method further includes performing knowledge distillation on the first neural network based on a target loss constructed by using the first target output and the second target output.

  • Patent number: 8164345
    Abstract: Design for testability (DFT) algorithms, which use both gradient descent and linear programming (LP) algorithms to insert test points (TPs) and/or scanned flip-flops (SFFs) into large circuits to make them testable are described. Scanning of either all flip-flops or a subset of flip-flops is supported. The algorithms measure testability using probabilities computed from logic simulation, Shannon's entropy measure (from information theory), and spectral analysis of the circuit in the frequency domain. The DFT hardware inserter methods uses toggling rates of the flip-flops (analyzed using digital signal processing (DSP) methods) and Shannon entropy measures of flip-flops to select flip-flops for scan. The optimal insertion of the DFT hardware reduces the amount of DFT hardware, since the gradient descent and linear program optimizations trade off inserting a TP versus inserting an SFF.

  • Patent number: 7702980
    Abstract: A scan-load-based (SLB) dynamic scan configuration reconfigures scan structures via scan-load operation, thereby eliminating interconnect network distributing configuration signals, and employs common scan circuitry identical for designs at mask level and is suitable for ASIC implementations. The architecture includes reconfigurable scan cells, apparatus for distributing configuration data to the reconfigurable scan cells and for determining desired reconfiguration data for each of the reconfigurable scan cells, and a configuration-set (CS) signal. Each of the reconfigurable scan cells has a pass-through (PT) mode in which data input, either a scan-in (SI) or a system-data (SD) of the scan cell, is transparently passed to a scan-out (SO) terminal of the scan cell without requiring a pulse on a shift clock (SC). The configuration-set (CS) signal communicates with each of the reconfigurable scan cells.

  • Patent number: 7535297
    Abstract: An architecture and method for improving efficiency of a Class-A power amplifier by dynamically scaling biasing current thereof as well as synchronously compensating gain thereof in order to maintain overall constant gain of the Class-A power amplifier at all biasing configurations thereof. A biasing-current switching-network is operatively connected to the back-end block of the Class-A power amplifier. A gain-control switching-network is operatively connected to a front-end block of the Class-A power amplifier. A detector-and-control block is operatively connected to an output of the back-end block of the Class-A power amplifier, and samples a signal that is then compared with reference signals to determine switching configurations in the biasing-current switching-network and the gain-control switching network when the signal is processed through the front-end block of the Class-A power amplifier followed by the back-end block of the Class-A power amplifier.

  • Patent number: 6922800
    Abstract: A method for improving the efficiency of test sequences for circuits with embedded multiple-port arrays, such as random access memory (RAM), is described, With existing test generation methods, it is a common occurrence that a resulting test sequence only utilizes a minimum number of read ports for detecting a target fault. When this type of test sequences is applied, one or more outputs of embedded RAMs may not attain known values, consequently reducing the effectiveness of the test sequences. The present invention enhances test sequences to that when they are applied, all outputs of embedded RAMs attain known values.

  • Publication number: 20020188904
    Abstract: A method for improving the efficiency of fault simulation using logic fault backtracing is described. With existing fault tracing methods, it is a common occurrence that too many faults are identified as potential faults to be processed by fault simulation. The method of the invention improves the fault-simulation efficiency by explicitly processing only those faults that are identified by logic fault tracing as potential faults. The present invention also reduces the storage usage with concurrent fault simulations.
