摘要：
Embodiments of this application provide a data bus inversion determining method, a circuit, and a device. The method includes: receiving N first input signals, where N is a positive integer; obtaining N first voltage signals based on the N first input signals, where the N first voltage signals are in one-to-one correspondence with the N first input signals; determining an average voltage value of the N first voltage signals; and determining, based on the average voltage value, whether to invert N second input signals, where the N first input signals are the same as the N second input signals, or the N first input signals are obtained based on the N second input signals. According to the method, the circuit, and the device in embodiments of this application, an average voltage value of N voltage signals is determined, and a determining result is used to determine whether to perform inversion and outputting. This avoids use of a large quantity of adder circuits and logic circuits, and greatly reduces an area, latency, and power consumption of the circuit.
