摘要
The operands of an N×M bit multiplication are partitioned into N/j+1 and M/k+1 bit signed submultiples. The most significant submultiple is assigned the sign of the operand, while each of the less significant submultiples is assigned a positive sign. The product of each submultiple pair is sign extended to the width of the product (N+M), and the accumulation of these sign extended submultiple products provides the product of the original twos complement operands, in twos complement form.
