The design implements a moving average filter using a series of registers and a finite state machine (FSM). The filter calculates the average of a set of recent values in a data stream, determined by the FILTER_POWER parameter. This smooths out short-term fluctuations and highlights longer-term trends or cycles. The master module handles input and output processing, including bidirectional IO handling and filter selection based on input control signals.
To test the moving average filter, provide a series of digital input values to the 'ui_in' port and observe the smoothed output on 'uo_out'. The 'uio_in' can be used to control the filter's width and operational parameters. Test with varying input patterns and filter widths to evaluate the filter's response.
