(Verilog) Square Root Carry Select Adder

Square Root Linear Carry Select

Hello,

I am trying to find or get a boolean expression for a square root linear carry select.

I am trying to program one in Verilog. If I can get a boolean expression then it would be a lot easier for me to program. If I can get one with "sum =...." and "carry/cin = ...." that would also be a plus.

I tried looking on google and here, and I can't seem to find any boolean expression for square root. The only one that I can find that is close is carry select.

Thank you for the help.

Hello,

I am trying to program in Verilog a square root carry select adder. However, if I can get the boolean expression of the square root adder it would make my task alot easier. I tried looking online for a boolean expersion, but I counldn't find one for square root adder.

If I can get the expression in "sum = ...." and "carry/cin = ..." then it would be a plus.

Thank you for the help.

The Boolean expression for a Square root adder and a carry select adder are the same. A square root adder is a specific implementation of the carry select adder. It consists of blocks of CSA's.

The first block is a 2 bit wide carry select adder, the second block is a 3 bit wide CSA, 3rd is 4bit CSA, then a 5 bit, 6bit, 7bit, etc.

The reason for this structure is to take advantage of gate delay
