ABSTRACT:
A multiplying circuit (10) receives a multiplicand A and multiplies it by multiplier B. An Octal recoder (18) recodes the multiplier B into octal digits having a value from 4 to -4. A tripling generator determines the product of three times the multipicand. Partial product generators (22a-h) connected to the Octal recoder multiplex between the multiplicand A and the 3*A product, and include shifter and inverter circuitry to generate the partial products. Signed digit adders (24a-d, 26a-b and 28) add the partial products.
