A method of operating a reconfigurable logic circuit includes; receiving a video sequence, profiling throughput of the video sequence with regard to a parameter constituting the reconfigurable logic circuit to generate a profiling result, initializing the parameter to a maximum value, evaluating throughput of the video sequence with regard to a current parameter value based on the profiling result, decreasing the current parameter value when throughput with regard to the current parameter value is not a maximum value, and determining that the current parameter value is an optimal parameter when throughput with regard to the current parameter value is the maximum value, and analyzing the video sequence based on the optimal parameter.
