MODULO 3 ADDER Russian patent published in 1994 - IPC

FIELD: computer engineering. SUBSTANCE: store-and-forward multiplier functions as follows. More significant bit a₂ and less significant bit b₁ of operand A=2a₂+a₁, more significant bit b₂ and less significant bit b₁ of operand B=2b₂+b₁, mode significant bit c₂ and less significant bit c₁ of operand C=2C₂+c₁ go to device inputs, where a₁,b₁,c₁,a₂,b₂,c₂∈{0,1} and A,B, C ∈(0,1,2). Two-bit code S=2s₂+s₁ of the result of multiplication of two numbers A and B followed by modulo 3 addition with number C, that is, S = A.B + C (mod. 3), is shaped across device outputs. EFFECT: enlarged functional capabilities due to implementing store-and-forward multiplication in device. 1 dwg, 1 tbl
