  • Patent number: 10539614
    Abstract: Embodiments of the present disclosure provide a method, a system, and a computer readable storage medium for circuit design verification. The user generates a breakpoint by execution of test bench code. A callback function is registered at an application level associated with the breakpoint. The callback function is configured to execute in response to an occurrence of the associated breakpoint at the system level. A hardware-accelerated simulator simulates an execution of a circuit design using the test bench code. In response to triggering the breakpoint at the system level, the execution of the circuit design at the system level is paused and the callback function associated with the breakpoint at the application level is executed.

  • Patent number: 10530629
    Abstract: Communication systems are described that use signal constellations, which have unequally spaced (i.e. ‘geometrically’ shaped) points. In many embodiments, the communication systems use specific geometric constellations that are capacity optimized at a specific SNR. In addition, ranges within which the constellation points of a capacity optimized constellation can be perturbed and are still likely to achieve a given percentage of the optimal capacity increase compared to a constellation that maximizes dmin, are also described. Capacity measures that are used in the selection of the location of constellation points include, but are not limited to, parallel decode (PD) capacity and joint capacity.

  • Patent number: 10524139
    Abstract: Communication systems are described that use signal constellations which have unequally spaced (i.e. “geometrically spaced,” or “non-uniform”) points. In many embodiments, the transmitters and receivers use specific non-uniform quadrature amplitude modulation (NU-QAM) constellations. In a variety of embodiments, NU-QAM constellations are capacity optimized using a bit-interleaved coded modulation (BICM, also referred to as “parallel decode”) capacity measure. In a number of embodiments, the transmitters and receivers are described that use specific NU-QAM constellations that provide gains in BICM capacity relative to constellations that maximize the minimum distance between constellation points.

    Abstract: Communication systems are described that use signal constellations, which have unequally spaced (i.e. ‘geometrically’ shaped) points. In many embodiments, the communication systems use specific geometric constellations that are capacity optimized at a specific SNR, over the Rayleigh fading channel. In addition, ranges within which the constellation points of a capacity optimized constellation can be perturbed and are still likely to achieve a given percentage of the optimal capacity increase compared to a constellation that maximizes dmin, are also described. Capacity measures that are used in the selection of the location of constellation points include, but are not limited to, parallel decode (PD) capacity and joint capacity.

  • Publication number: 20190116509
    Abstract: Communication systems are described that use geometrically shaped constellations that have increased capacity compared to conventional constellations operating within a similar SNR band. In several embodiments, the geometrically shaped is optimized based upon a capacity measure such as parallel decoding capacity or joint capacity. In many embodiments, a capacity optimized geometrically shaped constellation can be used to replace a conventional constellation as part of a firmware upgrade to transmitters and receivers within a communication system. In a number of embodiments, the geometrically shaped constellation is optimized for an Additive White Gaussian Noise channel or a fading channel. In numerous embodiments, the communication uses adaptive rate encoding and the location of points within the geometrically shaped constellation changes as the code rate changes.

  • Patent number: 10149179
    Abstract: Transmitters are described that use non-uniformly spaced symbol constellations that have increased capacity compared to conventional constellations. In many embodiments, a transmitter includes a coder configured to receive bits and output encoded bits, a mapper configured to map said encoded bits to symbols in a non-uniform symbol constellation selected from a plurality of symbol constellations, and a modulator configured to generate a signal for transmission via the communication channel using symbols generated by the mapper. In a variety of embodiments, wherein the non-uniform symbol constellation comprises a set of non-uniformly spaced constellation points, and the location points in the non-uniform symbol constellation are chosen to optimize parallel decode capacity of the non-uniform symbol constellation subject to at least one optimization constraint. In many embodiments, the non-uniform symbol constellation is a quadrature amplitude modulation constellation or a phase shift keyed constellation.

  • Publication number: 20180144154
    Abstract: Examples are disclosed that relate to providing healthcare-related information. One example provides a computing device comprising a logic machine and a storage machine holding instructions executable by the logic machine to receive an input of information regarding a health state of a user, obtain, based upon the information regarding the health state of the user, an inference of a possible health condition of the user, output a notification of the inference, the notification comprising a first representation of the inference, receive data representing a mechanism for authorizing a healthcare practitioner to access a second representation of the inference, and output a user-selectable control for triggering the mechanism. The instructions may be further executable to receive an input via the user-selectable control triggering the mechanism, and, in response, send authorization to provide the healthcare practitioner with access to the second representation of the inference.
