# Booth Multiplier
|
|
|
|
|
|
|
|
|
|
Sequentially multiply two signed twos-compliment integers in
|
|
|
|
|
Verilog using the [Booth Algorithm][1].

This design has been sucessfully synthesized with F4PGA
|
|
|
|
|
(`5aafae65883e95e41de2d0294729662dbe0a34f5`) on a Digilent Arty A7-35T
|
|
|
|
|
running at a clock speed of 100MHz. The test design is in `arty_test`.

## Usage
|
|
|
|
|
|
|
|
|
|
Set parameters `A1_LEN` and `A2_LEN` to the argument size of the
|
|
|
|
|
first and second integer. Set `A2LEN_SIZ` equal to
|
|
|
|
|
`floor(log2(A2_LEN) + 1)`.
|
|
|
|
|
|
|
|
|
|
After inputting each integer, pulse `arm` and wait until `fin` goes
|
|
|
|
|
high to retreive the output in `outn`.
|
|

## Simulating
|
|
|
|
|
|
|
|
|
|
Simulation is done with Verilator. Run `make`.
