ABSTRACT:
A multifunction arithmetic indicator that is associated with and controlled by an arithmetic logic unit (ALU) to store standard arithmetic indicator information such as overflow, carry, arithmetic sign and all bits equal zero that are generated by the ALU when processing binary information. A control unit sends control signals to multiplexers in the multifunction arithmetic indicator that cause the selection of appropriate arithmetic indicator information from the ALU, no matter what the bit length of binary words being processed by the ALU. The selected indicator information is stored in a register for later use.
