Handshake protocol synchronizer with low power consumption and corresponding method

The invention relates to the technical field of data processing, and provides a handshake protocol synchronizer with low power consumption and a corresponding method. The handshake signal control circuit judges whether a handshake signal is allowed to be generated and output or not; the handshake signal processing circuit notifies the upstream host to receive input data, generate output data and send the output data to the downstream slave; and the data processing circuit receives the input data, registers the input data according to the input handshake signal, the output handshake signal and the demultiplexing selection of the data input control circuit on the input data, acquires the output data according to the multiplexing selection of the data output control circuit on the output data, and sends the output data to a downstream slave. By optimizing the circuit structure, the complexity of the circuit is reduced, and the chip area is reduced. By designing the data input control circuit, the data register c
