B. Stepanov, Y. Diachenko, Y. Rogdestvenski, D. Diachenko. Self-timed multiplier for multiply-add unit // NW Russia Young Researchers in Electrical and Electronic Engineering Conference (EIConRusNW), 2016 IEEE. P. 349 – 352.  (is indexed in Scopus).

Paper discusses the peculiarities of self-timed multiplier implementation for unit multiplying two operands and then adding the product to third operand without an intermediate rounding according to the IEEE 754 Standard. The multiplier is a hardware implementation of modified Booth algorithm on a base of self-timed adder with redundant signal code. An optimal self-timed redundant coding of internal and output signals in the multiplier was proposed. The circuitry and layout problems were solved for self-timed multiplier implementation. Wallace tree structure, which is the main part of the multiplier, was optimized for the facilities of 65-nm CMOS process with six metal layers taking into account more number of signals in the multiplier circuit, than in the synchronous analog. A release of the self-timed multiplier implementation in CMOS process with 65-nm design rules is introduced
