Do CPUs have big circuits such as asynchronous multipliers or BCD to binary converters?An asynchronous multiplier is much bigger than an adder. It's about 18*n^2 NOR gates where n is the number of bits. An adder is about 15*n NOR gates. But for a 32-bits multiplication, a multiplier with successive additions will need 32 clock cycles, while an asynchronous mutliplier only 1. I think it's a big performance gain.The same is for BCD to binary converter.
