DEVICE AND METHOD FOR DUAL-MODE LOGIC

摘要

A dual-mode logic gate, for selectable operation in either of static and dynamic modes, includes: a static gate which includes at least one logic input and a logic output; a mode selector, configured for outputting a turn-off signal to select static mode operation and for outputting a dynamic clock signal to select dynamic mode operation; and a switching element associated with the mode selector static gate, comprising a first input connected to a constant voltage, a second input for inputting the mode selection signal from the mode selector, and an output connected to a logic output of the static gate. The switching elements switches the logic gate operation from static to dynamic mode, by applying the appropriate signal to the switching element.

1. A dual-mode logic gate, for selectable operation in either of static and dynamic modes, comprising:
a static gate comprising, at least one logic input and a logic output; a mode selector, configured for outputting a turn-off signal to select static mode operation and for outputting a dynamic clock signal to select dynamic mode operation; and a switching element associated with said mode selector static gate, comprising a first input connected to a constant voltage, a second input for inputting said mode selection signal from said mode selector, and an output connected to a logic output of said static gate, configured to: i) disconnect said static gate output from both of said first and second inputs when said mode selector applies said turn-off signal to said second input; and ii) connect said static gate output to both of said first and second inputs when said mode selector applies said dynamic clock signal to said second input.
