CarrySaveMultiplier class
A binary multiplier using carry-save technique with pipelining.
Reduces calculation time and complexity by employing the carry save multiplier, which splits numbers into smaller components and performs partial multiplications on each component separately, storing the results in a compact form. The pipeline enhances performance by breaking down the multiplication process into sequential stages, allowing for concurrent execution of multiple operations.
The latency of the carry save multiplier is the sum of the two inputs width
a
and b
.
