FIR Filter
Hard · Sequential · SystemVerilog
Implement a parameterized direct-form FIR (Finite Impulse Response) filter that computes the convolution of the last NUM_TAPS input samples with a static coefficient array.
**Filter equation**
The filter output at time $n$ is defined as:
$y[n] = \sum_{k=0}^{NUM\_TAPS-1} h[k] \cdot x[n-k]$
where $h[k]$ are the filter coefficients supplied via {coeffs} and $x[n-k]$ are the current and previous input samples stored in an internal shift register.
