Abstract

Methods, systems and computer program products for computing and summing up multiple products in a single multiplier are provided. Aspects include receiving a first number and a second number, creating partial products of the first number and the second number based on a multiplication of the first number and the second number, and reducing the number of partial products to create an intermediate result. Aspects also include receiving a third number and a fourth number, creating partial products of the third number and the fourth number based on a multiplication of the third number and the fourth number, creating a reduction tree and adding the intermediate result to the reduction tree. Aspects further include reducing the number of partial products in the reduction tree to create a second sum value and a second carry value and adding the second sum value and the second carry value to create a result.
