In this paper, we present a new approach to designing optical digital arithmetic systems. We present new arithmetic algorithms based on a modified signed-digit number representation. New Signed-digit symbolic substitution rules are introduced. to implement them. These signed-digit arithmetic algorithms are well suited for optical implementation because, of the confined carry propagation within adjacent digits. We present an optical architecture of such an arithmetic processor. The proposed optical arithmetic processor can potentially achieve 0(102) to 0(103) improvement in speed as compared with conventional electronic arithmetic processors.
