    摘要: One aspect provides a programmable logic device. The device includes an input circuit for detecting a multi-level input signal and an output circuit. The input circuit includes: an input pin for receiving the multi-level input signal; first and second programmable voltage generators to generate, respectively, first and second multi-level voltage signals; a pair of comparators, each comparator having a first input coupled to the input pin and a second input coupled to a corresponding programmable voltage generator; and a logic gate coupled to the comparators, thereby facilitating the detection of the multi-level input signal based on outputs of the comparators. The output circuit includes a third programmable voltage generator to generate a third multi-level voltage signal, an output pin, and a voltage buffer coupling the third programmable voltage generator to the output pin, thereby facilitating the programmable logic device to output, over the output pin, the third multi-level voltage signal.

    摘要: A programmable logic circuit device includes: a processor; and plural reconfiguration regions each including a circuit configured by change of connection between elements. The processor is configured to: upon detection of an abnormality while performing processing in a state in which the elements in the reconfiguration regions are connected in accordance with reconfiguration data designating connection between the elements in the reconfiguration regions, acquire reconfiguration data designating such connection between the elements that the processing being performed is not performed; and change connection between the elements in the reconfiguration regions in accordance with the designation by the acquired reconfiguration data.

    摘要: Methods and apparatuses to provide FPGA neighbor output mux direct connections to reduce, and potentially minimize, routing hops are described. Embodiments described herein include the addition of direct connections from one tile to the output muxing of a neighboring tile. An FPGA apparatus includes a plurality of logic block tiles. One or more direct connections extend from one or more logic block tiles of the plurality of logic block tiles to one or more inputs of output multiplexors (muxes) of one or more neighboring logic block tiles. The one or more direct connections are configured to drive one or more wires that start at the one or more neighboring logic block tiles.

    摘要: Techniques and mechanisms for determining an amount of skew between two clock signals. In an embodiment, detector circuitry receives a first signal and a signal which indicate (respectively) a NAND combination of clock signals, and a NOR combination of the clock signals. The detector circuitry evaluates a first length of time that the first signal indicates a respective first logic state, and a second length of time that the second signal indicates a respective second logic state. The skew is calculated based on a difference between the first length of time and the second length of time. In another embodiment, one of the first signal or the second signal is generated with a combinatorial logic gate, a transistor of which is relatively large, as compared to another transistor which is to operate based on one of the first signal, the second signal, or the clock signals.

    摘要: A semiconductor device includes a ROM, a differential sense amplifier and a multiplexer logic circuit. The ROM has memory cells in rows along word lines and columns along bit lines, and a reference column having reference transistors along a reference bit line. The multiplexer logic circuit couples a selected bit line to a first differential amplifier input and couples the reference bit line to the second differential amplifier input and controls a reference current of the reference bit line to be between a first bit line current of a programmed memory cell and a second bit line current of an unprogrammed memory cell.
