FUNCTIONAL STRUCTURES FOR PARALLEL-SERIAL RIPPLE CARRY f(←←)и f(←←) IN CONDITIONAL "i" "FORMATION ZONE" FOR CORRECTING RESULTANT PRELIMINARY FIRST LEVEL SUM OF ARGUMENTS OF PARTIAL PRODUCTS OF PARALLEL-SERIAL MULTIPLIER f(Σ) OF POSITIONAL FORMAT OF MULTIPLICAND [m]f(2) AND MULTIPLIER [n]f(2) (VERSIONS) Russian patent published in 2011 - IPC G06F7/506

Abstract RU 2431886 C1

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.
