    Abstract: A floating-point fused multiply-add (FMA) unit embodied in an integrated circuit includes a multiplier circuit cascaded with an adder circuit to produce a result A*C+B. To decrease latency, the FMA includes accumulation bypass circuits forwarding an unrounded result of the adder to inputs of the close path and the far path circuits of the adder, and forwarding an exponent result in carry save format to an input of the exponent difference circuit. Also included in the FMA is a multiply-add bypass circuit forwarding the unrounded result to the inputs of the multiplier circuit. The adder circuit includes an exponent difference circuit implemented in parallel with the multiplier circuit; a close path circuit implemented after the exponent difference circuit; and a far path circuit implemented after the exponent difference circuit.

    Abstract: A chip generator according to an embodiment of the present invention codifies designer knowledge and design trade-offs into a template that can be used to create many different chips. Like reconfigurable designs, an embodiment of the present invention fixes the top level system architecture, amortizes software and validation and design costs, and enables a rich system simulation environment for application developers. Meanwhile, below the top level, the developer can “program” the individual inner components of the architecture. Unlike reconfigurable chips, a chip generator according to an embodiment of the present invention, compiles the program to create a customized chip. This compilation process occurs at elaboration time—long before silicon is fabricated. The result is a framework that enables more customization of the generated chip at the architectural level because additional components and logic can be added if the customization process requires it.

    Abstract: Optical signals are passed in an optical medium using an approach that facilitates the mitigation of interference. According to an example embodiment, a filtering-type approach is used with an optical signal conveyed in an optical fiber, such as a multimode fiber (MMF) or a multimode waveguide. Adaptive spatial domain signal processing, responsive to a feedback signal indicative of data conveyed in the multimode waveguide, is used to mitigate interference in optical signals conveyed in the multimode waveguide.

    Abstract: An input data sequence is sampled according to a sampling clock such that a first set of samples corresponds to data values and a second set of samples corresponds to edges between the data values. The phase error between data transitions in the input sequence and the sampled edges is determined based on amplitudes of the sampled edges. The sampling clock's phase is adjusted based on the determined phase error. Typically, the phase error is proportional to an amplitude of a sampled edge. Sampled edge amplitude values are added or subtracted, according to the direction of each transition about each edge to form an error value which indicates the amount phase error.

    Abstract: A method and system for transferring information within a computer system is provided. The system includes a memory device that has a lower power mode in which data transfer circuitry is not driven by a clock signal, and a higher power mode in which data transfer circuitry is driven by a clock signal. The system further includes a memory controller that sends control signals to the memory device to initiate a data transfer transaction. The memory device receives the control signals asynchronously, and assumes the second mode in response to one of the control signals. While the memory device is in the second mode, the memory controller sends a control signal to identify a particular clock cycle. The memory device synchronously transfers the data. The memory device determines when to begin the data transfer based on the identified clock cycle and the type of data transfer that has been specified.

    Abstract: A semiconductor memory device has a memory core that includes at least eight banks of dynamic random access storage cells and an internal data bus coupled to the memory core. The internal data bus receives a plurality of data bits from a selected bank of the memory core. The semiconductor memory device further comprises a first interface to receive a read command from external to the semiconductor memory device and a second interface to output first and second subsets of the plurality of data bits. The first subset is output during a first phase of an external clock signal and the second subset is output during a second phase of the external clock signal. The first phase includes a first edge transition and the second phase includes a second edge transition. The second edge transition is an opposite edge transition with respect to the first edge transition.
