FUNCTIONAL STRUCTURES FOR PARALLEL-SERIAL RIPPLE CARRY f_j+1(←←)⁺ и f_j(←←)⁺ IN CONDITIONAL 'i' 'FORMATION ZONE' FOR CORRECTING RESULTANT PRELIMINARY FIRST LEVEL SUM OF ARGUMENTS OF PARTIAL PRODUCTS OF PARALLEL-SERIAL MULTIPLIER f_Σ(Σ) OF POSITIONAL FORMAT OF MULTIPLICAND m_jf(2ⁿ) AND MULTIPLIER n_if(2ⁿ) (VERSIONS)

摘要

FIELD: information technology.;SUBSTANCE: invention can be used when designing arithmetic units and performing arithmetic operations, particularly preliminary summation of arguments of a multiplicand [m_j]f(2ⁿ) in positional format. In one version of the invention, functional structures are in form of two structure-equivalent logic carry-over functions of the j-th and (j+1)-th bits, where each bit contains elements performing AND, OR and NOT logic functions.;EFFECT: faster ripple carry process.;10 cl, 5 ex
