Witryna21 lut 2024 · The number of select lines required is determined by n --> i.e., SHIFT_CNT = log2 (NUMBITS-1)+1 in the code below. It's considered bad form in my organization (and I think overall) to have ports that are not of std_logic_vector or std_logic, so I used a std_logic_vector for the number of select lines.
