摘要： A ring oscillator based voltage controlled oscillator (VCO) is disclosed. The VCO includes a set of delay cells connected to each other in a ring configuration. Each of the delay cells includes a source-coupled input transistor pair, a current-steering transistor pair and a pair of load resistors. The source-coupled input transistor pair receives a pair of differential voltage inputs. The load resistors, which are connected to the source-coupled input transistor pair, provide a pair of differential voltage outputs. The current-steering transistor pair, which is connected to the source-coupled input transistor pair, receives a pair of differential bias voltage inputs. The output frequency of the VCO is directly proportional to the differential bias voltages at the pair of differential bias voltage inputs.

摘要： A three-path floating-point fused multiply-adder is disclosed. The fused multiply-adder is for the single instruction execution of (A×B)+C. The three-path fused multiply-adder is based on a dual-path adder and reduces latency significantly by operating on case data in parallel and by reducing component bit size. The fused multiply-adder is a common serial fused multiply-adder that reuses floating-point adder (FPA) and floating-point multiplier (FPM) hardware, allowing single adds, single multiplies, and fused multiply-adds to execute at maximum speed.

摘要： A fused floating-point add-subtract unit includes far path logic, close path logic, and selection logic. The far path logic is configured to perform addition and subtraction operations on first and second significands of first and second operands, respectively, to produce a far path sum and a far path difference. The close path logic is configured to perform addition and subtraction operations on the first and second significands of the first and second operands, substantially concurrently with the addition and subtraction operations of the far path logic, to produce a close path sum and a close path difference. The selection logic selectively provides one of the far path sum and the close path sum as a significand of a sum output and one of the far path difference and the close path difference as a significand of a difference output.

摘要： A modular pipeline algorithm and architecture for computing discrete Fourier transforms is described. For an N point transform, two pipeline √{square root over (N)} point fast Fourier transform (FFT) modules are combined with a center element. The center element contains memories, multipliers and control logic. Compared with standard N point pipeline FFTs, the modular pipeline FFT maintains the bandwidth of existing pipeline FFTs with reduced dynamic power consumption and reduced complexity of the overall hardware pipeline.

摘要： A bridge fused multiply-adder is disclosed. The fused multiply-adder is for the single instruction execution of (A×B)+C. The bridge fused multiply-add unit adds this functionality to existing floating-point co-processor units by including a fused multiply-add hardware “bridge” between an existing floating-point adder and a floating-point multiplier unit. This fused multiply-add functionality is added to existing two-operand architecture designs without degrading the performance or parallel pipe execution of floating-point adder and floating-point multiplier instructions.

摘要： The present disclosure relates to methods and systems for data tag control for quantum dot cellular automata (QCA). An example method includes receiving data, associating a data tag with the data, communicating the data tag along a first wire-like element to a local tag decoder, reading instructions from the data tag using the local tag decoder, communicating the instructions to a processing element, communicating the data along a second wire-like element to the processing element, and processing the data with the processing element according to the instructions. A length of the first wire-like elements and a length of the second wire-like element are approximately the same such that communication of the instructions and the data to the processing element are synchronized.

摘要： Techniques are generally described that include methods, devices, systems and/or apparatus for dividing a numerator by a denominator. Some example methods may include selecting a first numerical factor stored in an electronic storage media. The first numerical factor may be multiplied by a numerator at least in part using a first logic circuit configured to perform multiplication. The first numerical factor may also be multiplied by a denominator. A second numerical factor may be calculated based, at least in part, on an approximation of a square of the difference between unity and the product of the first numerical factor and the denominator. The second numerical factor may be multiplied by the product of the numerator and the first numerical factor at least in part using the first logic circuit, to generate an approximation of a quotient of the numerator and the denominator.

摘要： A method and apparatus for capacitance multiplication using two charge pumps. A first charge pump (206) provides a current signal (I216) that is first conducted by a resistor (310) of an RC network and then split into three current paths prior to being conducted by a capacitor of the RC network. A first current path provides current to the capacitor (306) of the RC network from node (320). A second current path multiplies the current conducted by capacitor (306) by a first current multiplication factor. A third current path provides current to a second charge pump, which multiplies the current from the first charge pump by a second current multiplication factor that has a fractional value with an inverse magnitude sign relative to the first current multiplication factor. The combination of the second and third current paths effectively multiplies the capacitance magnitude of capacitor (306).
