adder (<a class="el" href="classadder__gen.html">adder_gen</a>), multiplier (<a class="el" href="classmultiplier__gen.html">multiplier_gen</a>), and delay (<a class="el" href="classdelay__gen.html">delay_gen</a>). <br/>

The top-level is a structural description in a generic/scalable form. <br/>

The filter coefficients and the quantization bit width should be edited/pasted <br/>

| 81 |

into the <a class="el" href="fir__pkg_8vhd.html" title="This is the supporting package. "JUST EDIT THIS FILE".">fir_pkg.vhd</a>. The filter coefficients should be given in integer format. <br/>

Design specs: <br/>
|
| 83 |
|
|
Unsigned single/multi-bit input (fir_in) <br/>
|
| 84 |
|
|
Signed multi-bit output (fir_out) <br/>

Rising edge clock (fir_clk) <br/>
