LOGIC CIRCUIT AND SYSTEM AND COMPUTER PROGRAM PRODUCT FOR LOGIC SYNTHESIS

摘要

A logic circuit includes first and second input, an output, an input acknowledgement node, an output acknowledgement node, a logic evaluation block, a pre-charging circuit, and a completion detection circuit. The logic evaluation block performs a logic evaluation of first and second input signals at the first and second inputs, and to output an output signal corresponding to the logic evaluation. The pre-charging circuit pre-charges the logic evaluation block in response to the first input signal and an acknowledgement signal at the input acknowledgement node. The completion detection circuit generates an acknowledgement signal at the output acknowledgement node in response to the second input signal and the output signal.
