Title: The multiplier circuit
Inventor: BYUN HYEON IL
IPC: G06F7/52
Filed: 2001-10-11
Abstract: PURPOSE: A multiplier circuit is provided to remove unnecessary output bits from a conventional multiplication circuit so that it can reduce a delay time from a data input from a data output, and a consumption power. CONSTITUTION: The circuit comprises a multiplier(401), an overflow checker(402) and a selector(403). The multiplier(401) receives N bit data and M bit data, and multiplies the N bit data by the M bit data while limiting the multiplication output within L bits where L is not over N + M. The overflow checker(402) checks whether there occurs an overflow at the output from the multiplier(401) by referring to the carry data of (N + M) - L. The selector(403) outputs the largest number which can be expressed with the L bits if there occurs an overflow at the output from the multiplier(401), and, otherwise, outputs the multiplication result with the L bits.
