Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to a reconfigurable dynamic logic gate circuit. Background technique [0002] An important research direction of next-generation computer chip design research is to make computing devices have a reconfigurable dynamic logic architecture. The existing reconfigurable dynamic logic architectures are all based on the traditional programmable logic gate array (FPGA) technology. FPGA technology is to reconnect the static wiring on the integrated circuit chip to achieve different functions. Its single logic gates are not reconfigurable. However, traditional logic gate circuits are generally composed of single-selection switch circuits. The gate circuits can only be set in advance and cannot be dynamically converted. The prior art also has a binary logic gate circuit composed of a double selection switch circuit, which realizes the conversion between "AND gate" and "OR gate". ...
