of the multiplier. In another embodiment of the present invention, HDL description 605 may contain computer readable codes that define steps of the tree reduction process 600 in HDL (e.g., VHDL, Verilog, etc). At step 610, the process 600 of the present embodiment constructs an input ...
To solve this difficulty, we described a C program which automatically generates a Verilog file for a Dadda multiplier with Parallel Prefix adders like Kogge-Stone adder, Brent-Kung adder and Han-Carlson adder of user defined size. We compared their post layout results which include propagation ...

The multiplier concurrently adds the partial products bits generated with the accumulator bits. The design implementation is described in both at gate level and high level RTL code (behavioural level) using Verilog Hardware Description Language. The design code is tested using Veriwell Simulator. The ...
Three consecutive bits of the multiplier are encoded to produce an x2,a,s control value that is used, in turn, to choose a single partial product term. The next 3 bit window of multiplier bits overlaps the first window by one bit. The encoding is as follows: // {booth_a,booth_s}...
For performance investigation, we have compared dedicated multiplier architectures with scalable design. After this, the dedicated and scalable architectures are compared with the most relevant state-of-the-art multipliers. All multiplier architectures are implemented in Verilog HDL using the Vivado IDE ...
