Abstract
The principles of the present invention relate to a multiply and divide circuit configured to interactively multiply and/or divide. The circuit may handle signed and unsigned values. The circuit comprises an instruction register configured to store a multiply or divide instruction, at one input register configured to store the multiply or divide operands, an Arithmetic Logic Unit ('ALU') configured to add provided values, and configuration circuitry. The configuration circuitry responds to the instructions and performs the multiply or divide operation by iteratively providing values to the ALU.
