Abstract
The present disclosure provides a data mutex filter circuit and a data mutex filtering method. The data mutex filter circuit has a main input terminal and a main output terminal and including a preprocessing sub-circuit and a 1st-stage filter sub-circuit to an Nth-stage filter sub-circuit which are cascaded, N being an integer greater than or equal to 2. The 1st-stage filter sub-circuit has an input terminal coupled to the preprocessing sub-circuit, and the Nth-stage filter sub-circuit has an output terminal coupled to the main output terminal. Each stage of filter sub-circuit is configured to compare whether input data currently received at the main input terminal is the same as history data stored therein, and feed back a comparison result to the preprocessing sub-circuit; the preprocessing sub-circuit outputs corresponding data to the 1st-stage filter sub-circuit according to the comparison result fed back by each stage of filter sub-circuit.
