Pipelined Direct Form FIR Versus the Transposed Structure

This article will review two different structures to implement a high-throughput FIR (finite impulse response) filter: the pipelined direct form FIR and the transposed structure. We’ll see that generally the transposed structure is the preferred implementation for a FIR filter.

Basic Binary Division: The Algorithm and the VHDL Code

Based on this algorithm, we’ll derive a block diagram for the circuit implementation of binary division. Finally, we’ll look at the ASMD (Algorithmic State Machine with a Data path) chart and the VHDL code of this binary divider. Consider dividing 11000101 by 1010.
