This paper presents a class of complex number representations called Redundant Complex Number Systems (RCNSs), which are useful for designing VLSI signal processors with complex arithmetic capability. A redundant complex number system is defined as an imaginary-radix number system having a redundant integer digit set. This makes possible the construction of high-speed complex arithmetic circuits: examples include a complex-number parallel adder with no carry propagation chain, and a complex-number multiplier using fast binary-tree addition structure. This paper also presents the experimental fabrication of the RCNS-based complex multiplier in 0.5 μm CMOS technology.
