Abstract
The implementation of the mantissa portion of a floating-point multiply (54/spl times/54b) is described. The 0.124mm/sup 2/ multiplier is implemented using limited switch dynamic logic and operates at speeds up to 8GHz in a 90nm SOI technology. The multiplier dissipates between 150mW and 1.8W as it scales between 2GHz and 8GHz.
