BOOTH CONVERSION CIRCUITS

摘要

The booth's algorithm conversion circuit has two swithches controlled by input signals QX and Q2X and receiving as input, signals Xi of a logic level positioned in the i digit order of a multiplicand X and signal Xi-1 of a logic level positioned in the i-l digit order of multiplicand X. The outputs of the switches are tied together and to ground via two transistors controlled by signals QX and Q2X, the transistors conducting in an inverse relationship to the switch circuits. The common output of the two switch circuits is input to an exclusive OR circuit which receives an additional logic 1 or logic 0 input signal to produce the Booth's converted output.
