Techniques are provided to permit a programmable logic device (PLD) to comply with a communication standard before the PLD is fully configured. In one example, a method includes programming a first portion of a programmable logic device (PLD) with first configuration data. After the first portion is programmed, the first portion is operated in accordance with a communication standard to exchange data with a host system while a second portion of the PLD is programmed with second configuration data.

A data processing device and an aerial vehicle are provided. The device comprises a sensor, a processor, and a clock converter. A data signal output pin of the sensor is connected with a data signal input pin of the processor. The sensor comprises at least two clock output pins, each of which is connected with one of two input pins of the clock convert. An output pin of the clock converter is connected with a clock input pin of the processor. The dock converter is configured to convert clock signals input from various input pins into a single-ended clock signal, and output the single-ended clock signal to the processor through the output pin.

A logic circuit includes a setting circuit which holds and outputs setting information, a first flip-flop which holds data written to the setting circuit and outputs it in synchronization with an inputted clock, a second flip-flop which holds a write address for selecting the setting circuit and outputs it in synchronization with the inputted clock, and a third flip-flop which holds write enable which allows writing to the setting circuit and outputs it in synchronization with the inputted clock, wherein the setting circuit includes a fourth flip-flop which holds the setting information in synchronization with a given timing signal, and a fifth flip-flop which holds the output of the third flip-flop and outputs a write clock to the fourth flip-flop as the timing signal in synchronization with the inputted clock.

A processing method according to an embodiment of the present disclosure includes: causing a computer to perform first processing for identifying one or a plurality of flip-flop circuits each forming a self-feedback loop from among a plurality of flip-flop circuits in a synchronous circuit, deleting a feedback path in the self-feedback loop, identifying two or more flip-flop circuits forming strongly coupled components from among the one or plurality of flip-flop circuits, and replacing the two or more flip-flop circuits forming the strongly coupled components with one dummy flip-flop circuit; and causing the computer to perform second processing for identifying first one or more flip-flop circuits coupled to input side of a combinational circuit and second one or more flip-flop circuits coupled to output side of the combinational circuit.

In one memory array embodiment, in order to compensate for bit-line leakage currents by OFF-state bit-cell access devices, a leakage-current reference circuit tracks access-device leakage current over different process, voltage, and temperature (PVT) conditions to generate a leakage-current reference voltage that drives a different leakage-current abatement device connected to each different bit-line to inject currents into the bit-lines to compensate for the corresponding leakage currents. In one implementation, the leakage-current reference circuit has a device that mimics the leakage of each access device configured in a current mirror that drives the resulting leakage-current reference voltage to the different leakage-current abatement devices.
