A high speed multiplier and divider for MOS LSI based on a new algorithm is presented. When we implement the multiplier and the divider in LSI, the features such as high speed operation, small number of transistors and easy layout are the most important factors. A computational algorithm using a redundant binary representation has several excellent features such as high speed addition operations. We improved the algorithm and the method of implementation, and designed an advanced multiplier and divider with the above mentioned features. We expect mat our multiplier and divider are excellent compared with multipliers using the Booth algorithm and the Wallace tree, and with divider using the SRT method, respectively.
