This paper presents a fast highly regular digit-serial complex-number multiplier-accumulator (CMAC) architecture which is well suited for VLSI implementations. This paper makes two contributions. First, several complex-number representation schemes are discussed. It is shown that the real-imaginary alternate (RIA) scheme is the best among all representation schemes and the prior designs of CMACs based on the radix-(2j) Redundant Complex Number System (RCNS) are not efficient with respect to hardware complexity and processing speed. Second, digit-serial CMAC architectures which can be pipelined at fine-grain level to increase the throughput rate are designed based on carry-save configuration.
