AN EFFICIENT BIT RATE PERFORMANCE OF SERIAL-SERIAL MULTIPLIER WITH 1’S ASYNCHRONOUS COUNTER

Traditional Serial-Serial multiplier address the high data sampling rate. It is effectively considered as the entire partial product matrix with n data sampling cycle for n×n multiplication function instead of 2n cycles in the conventional multipliers. The existing Serial-Serial multiplier is the first bit serial structure. Newly developed serialserial multiplier design is capable of processing input data at (GBs) without buffering and with reduced total number of computational cycle. This multiplication of partial products by considering two series inputs among which one is starting from LSB the other from MSB. Using this feed sequence and accumulation technique it takes only n cycle to complete the partial products. It achieves high bit sampling rate by replacing conventional full adder and highest 5:3 counters. Here asynchronous 1's counter is presented. This counter takes critical path is limited to only an AND gate and D flipflops. Accumulation is integral part of serial multiplier design. 1's counter is used to count the number of ones at the end of the nth iteration in each counter produces. The proposed multiplier consist of a serial-serial data accumulator module and carry save adder that occupies less silicon area than the full carry save adder. In this paper we proposed model address for the 8bit 2's complement implementing the Baugh-wooley algorithm and unsigned multiplication implementing the proposed architecture for 8×8 Serial-Serial unsigned multiplication. We can able to extend the 16bit multiplication.
