A 32-bit complex-arithmetic integer logic unit with dynamic accuracy

A pipelined 32-bits integer arithmetic unit with dynamic accuracy is described, that supports addition/subtraction, multiplication/division, power/root and a number of mixed operations such as sum of squares directly in hardware, and is easily extended for floating-point and adaptive accuracy computations. In a 0.8 /spl mu/m CMOS technology, this module houses 3k transistors on a 2.5 mm/sup 2/ area and operates at about 100 MHz external clock.
