Abstract
A multiplier includes a plurality of subunits. Each of the plurality of subunits is configured to perform a portion of a multiplication operation, and the plurality of subunits are coupled together to perform the multiplication operation. At least a first subunit of the plurality of subunits and a second subunit of the plurality of subunits are configured to perform a same portion of the multiplication operation. The first subunit and the second subunit are clocked at a first clock frequency, during use, that is less than a second clock frequency at which a remainder of the plurality of subunits are clocked during use. The first subunit and the second subunit each have inputs coupled to a third subunit of the plurality of subunits to receive multiplication operations to be operated upon by the respective first subunit and second subunit.
