OPTICAL DIGITAL PAGING FIXED-POINT MULTIPLIER Russian patent published in 1999 - IPC

FIELD: electronics. SUBSTANCE: device uses original algorithm for algebraic multiplication of pages of fixed point numbers and usage of original methods and connection s and transmission of operand pages, original operand shift circuits in digital adder, and circuits of unit which calculates signs of product. Device has input optical register for multiplicand, which has sign bits and main bits, optical connection unit, optical unit for calculation of sign of product, optical connection units, unit of optical gates, optical connection unit, optical digital adder, which has main and sign bits and additional bit, optical unit for additional single bit, optical connection unit, controlled shift register for factor, which has sign and main bits, bit optical gates, optical connection units, output optical register, which has sign and main bits respectively. EFFECT: increased reliability, simplified design, increased functional capabilities due to execution of operations in algebraic representation. 2 cl, 2 dwg
