An iterative pipeline carry save array multiplier module (PCAMM) is proposed which hasa constant through put rate for every number of data bits. Data in 2s complement form are processed directly according to the Robertson algorithm. The PCAMM was realized in ECL–technologyfor6–bit data with a throughput rate of 35 x 104multiplications per second. Multipliers ofthis kind are the heart of the 12–bit arithmetic unit of a fast signal processor which has been developed at Technical University of Munich.
