Large Comparators Pipelined Efficiently by Recursion

Amusing myself with recursive structures in HDL that are entirely synthesisable and optimal in both size and clock speed. This is primarily a mathematics problem, and once the VHDL construction has been completed, the EDA tools have a final twist.

Bus-width Polynomial Division Logic

Calculating the remainder after polynomial division modulo 2 multiple bits per clock cycle. This enables the calculation to keep pace with the presentation of a wide data bus. This article shows how VHDL and synthesis can automatically calculate the…
