<p>This is the top-level design for a transposed-form FIR digital filter. <br/>
47 
 It instantiate the three major components for constructing a digital filter such as; <br/>
48 
 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/>
49 
 The top-level is a structural description in a generic/scalable form. <br/>
50 
 The filter coefficients and the quantization bit width should be edited/pasted <br/>
51 
 into the <a class="el" href="fir__pkg_8vhd.html">fir_pkg.vhd</a>. The filter coefficients should be given in integer format. <br/>
52 
 Design specs: <br/>
53 
 Unsigned single/multi-bit input (fir_in) <br/>
54 
 Signed multi-bit output (fir_out) <br/>
55 
 Active high asynchronous reset (fir_clr) <br/>
56 
 Rising edge clock (fir_clk) <br/>
