According to one embodiment, a programmable logic assembly (200) may include a nonvolatile memory devices (202-0 and 202-1) coupled to an associated volatile programmable logic device (PLD) (204). Each nonvolatile memory device (202-0 and 202-1) may store different configuration data for a volatile PLD (204). Upon a predetermined event, such as powerup or reset, one of the nonvolatile memory devices (202-0 and 202-1) may be selected and its configuration data read into a volatile PLD (204).

An I/O cell of a programmable logic device comprising a register, a first multiplexer, a second multiplexer, and a third multiplexer. The first multiplexer may be configured to present one of a plurality of signals to a data input of the register in response to a control signal. The second multiplexer may be configured to select either an output signal from the register or an external input signal in response to the control signal. The third multiplexer may be configured to select one of a number of inputs for presentation as an output signal of the I/O cell in response to the control signal. The register may be configured as an internal register of the programmable logic device when the I/O cell is configured to receive a combinatorial input signal and/or present a combinatorial output signal.
摘要:
An ink jet printing ink is first formulated in concentrated form, and in this form it is subjected to stressful operating conditions such as an elevated temperature. This stress causes particle formation. After filtration to remove these particles, the final ink formulation is prepared, including for the first time ingredients which inhibit particle formation.
