document: One-step digit-set-restricted modified signed-digit adder using an incoherent correlator based on a shared content-addressable memory An efficient one-step digit-set-restricted modified signed-digit -LRB- MSD -RRB- adder based on symbolic substitution is presented . In this technique , carry propagation is avoided by introducing reference digits to restrict the intermediate carry and sum digits to -LCB- 1,0 -RCB- and -LCB- 0,1 -RCB- , respectively . The proposed technique requires significantly fewer minterms and simplifies system complexity compared to the reported one-step MSD addition techniques . An incoherent correlator based on an optoelectronic shared content-addressable memory processor is suggested to perform the addition operation . In this technique , only one set of minterms needs to be stored , independent of the operand length
