Abstract
The present invention simplifies a partial multiplier selector for a multiplication circuit using the Booth Algorithm. For this purpose, a partial multiplier selector according to the present invention comprises a multiplier register to store multiplier data, a plurality of partial multiplier selecting units comprising clocked inverters which divide the multiplier data stored in the multiplier register using the multiplication start signal and sequentially fetch them and control circuits comprising latch circuits which sequentially output the multiplication start signal to the partial multiplier selecting units with a delay of one clock using the clock signal.
