Abstract: A photonic random signal generator includes an incoherent optical source configured to generate an optical noise signal, a filter configured to generate a filtered optical noise signal using the optical noise signal, a coupler, a photodetector, a filter, and a limiter. The coupler couples the filtered optical noise signal and a delayed version of the filtered optical noise signal to generate a first coupled signal and a second coupled signal. The photodetector generates an output signal representative of a phase difference between the filtered optical noise signal and the delayed version of the filtered optical noise signal using the first coupled signal and the second coupled signal. The filter filters the output signal representative of the phase difference to generate an analog random signal. The limiter thresholds the analog random signal based on a clock signal, to generate a digital random signal.

Abstract: A multiply-accumulate (MAC) operation in a deep neural network (DNN) consists of multiplying each input signal to a node by a respective numerical weight data and summing the products. Using ternary values for the input signals and weight data reduces memory and processing resources significantly. By representing ternary values in two-bit binary form, MAC operations can be replaced with logic operations (e.g., XNOR, popcount) implemented in logic circuits integrated into individual memory array elements in which the numerical weight data are stored. In this regard, a ternary computation circuit (TCC) includes a memory circuit integrated with a logic circuit. A memory array including TCCs performs a plurality of parallel operations (e.g., column or row elements) and determines a popcount. A TCC array in which logic circuits in columns or rows employ a single read-enable signal can reduce routing complexity and congestion of a metal layer in a semiconductor device.

Abstract: A data processing system includes multiple processing units all having access to a shared memory. A processing unit of the data processing system includes a processor core including an upper level cache, core reservation logic that records addresses in the shared memory for which the processor core has obtained reservations, and an execution unit that executes memory access instructions including a fronting load instruction. Execution of the fronting load instruction generates a load request that specifies a load target address. The processing unit further includes lower level cache that, responsive to receipt of the load request and based on the load request indicating an address match for the load target address in the core reservation logic, protects the load target address against access by any conflicting memory access request during a protection interval following servicing of the load request.

Abstract: An execution unit is described which is particularly configured to generate an exponential of an operand floating point format. The operand is multiplied by a fixed multiplicand, logged to the base 2 (e) to generate a multiplication result. An integer part and a fractional part are extracted from the multiplication result. An exponent register stores the integer part to form the exponent of the exponential result. A lookup table has a plurality of entries each providing a value of 2f for a fractional part f used to access a lookup table. The fractional part is derived from a mantissa of the operand. That is, first and second bit sequences are extracted from the mantissa. One of the bit sequences is used to generate an estimated fractional component, and the other is used to access a value from the lookup table.

Abstract: A noise reduction filter for data signals is implemented using two orthogonal coordinates comprising intensity and differential intensity values generated from sampling and sorting the data signals. A weighting function is used to amplify or reduce different portions of a data set distribution generated using the intensity and differential intensity values. The weighting function may also include scalar constants to further enhance the capability of the noise reduction filter. The noise reduction filter can be used to reduce the noise components or increase the useful signal components of a noisy data signal, thereby increasing the signal-to-noise ratio, and also increasing spectral resolution. The noise reduction filter can also be used in special cases where the intensity and frequency spectra of the noisy data signal are overlapping. The noise reduction filter may be used in various applications including spectroscopy and image processing, among others.

Abstract: The present innovative solution solves the problem of generating pseudo-random numbers that have practically infinite period, while requiring limited processing resources and operating significantly faster that known pseudo-random number generators. A sequence of big pseudo-random numbers is created using a large seed number calculated as the product of three large constants entered by a user or fed by a computer clock. The big pseudo-random numbers are then selectively split into a sequence of aperiodic pseudo-random numbers which are then output for use in any suitable application and for seeding the present generator.
