Data Path Bit Width
The core supports signed and unsigned data and coefficients. The core can be configured accordingly. The
output data is unsigned, if both input data and coefficients are unsigned. Otherwise the output data is
signed. Input and output data, as well as the coefficients, are integers in two’s complement format.
The core supports signed data and coefficient of 2 to 18 bits. For the unsigned data and coefficients, the bit
width is limited to 17 bits.
Internal filter processing takes place at full precision to reduce truncation or rounding noise and avoid risk of
overflow. The filter output data are presented in full precision as well. If the data and coefficient bit widths
are DATA_WIDTH and COEF_WIDTH, and the number of filter taps = TAPS, then the full precision output
Output Bit Width = DATA_WIDTH + COEF_WIDTH + ceiling(log 2 (TAPS/L))
