摘要： 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.

摘要： 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.

摘要： A memory system includes a link having at least one signal line and a controller. The controller includes at least one transmitter coupled to the link to transmit first data, and a first error protection generator coupled to the transmitter. The first error protection generator dynamically adds an error detection code to at least a portion of the first data. At least one receiver is coupled to the link to receive second data. A first error detection logic determines if the second data received by the controller contains at least one error and, if an error is detected, asserts a first error condition. The system includes a memory device having at least one memory device transmitter coupled to the link to transmit the second data. A second error protection generator coupled to the memory device transmitter dynamically adds an error detection code to at least a portion of the second data.

摘要： A fault-tolerant clock generation circuit. First and second clock signal generators are provided to generate first and second clock signals. The second clock signal generator includes a locked loop circuit that, in a first operating mode, adjusts the phase of the second clock signal as necessary to maintain phase alignment between the first and second clock signals. A fail detect circuit is provided to determine whether a failure relating to generation of the first clock signal has occurred and, if so, to assert a hold signal. The locked loop circuit responds to assertion of the hold signal by transitioning to a second operating mode in which the phase of the second clock signal is not adjusted.

摘要： An integrated circuit memory device comprises a memory array to store data, a circuit to output the data at a pin, and a register to store a value that indicates a mode of operation of the integrated circuit memory device. The mode of operation is selected from at least one of a synchronous mode of operation and an asynchronous mode of operation. During the synchronous mode of operation, the circuit outputs the data in response to a transition of an external clock signal. During the asynchronous mode of operation, the circuit outputs the data after a period of time from when a transition of an external control signal is detected.

摘要： A signaling system having first and second sampling circuits and an output driver circuit. The first sampling circuit samples a first signal generated by the output driver circuit to determine whether the first signal exceeds a first threshold.

The drive strength of the output driver circuit is adjusted based, at least in part, on whether the first signal exceeds the first and second thresholds, and the second threshold is adjusted based, at least in part, on whether the first signal exceeds the second threshold.
