Abstract
A system and method for implementing arithmetic logic unit (ALU) support for value-based control dependence sequences. According to a first embodiment of the present invention, an ALU generates a carry-out signal designating one of a first and second value as a larger value. In response to the carry-out signal, the ALU updates a storage location with a third value, which is the larger value. According to a second embodiment of the present invention, an ALU generates a carry-out signal designating one of a first and second value as a larger value. In response to the carry-out signal, the ALU updates a storage location with a third value. The third value is a fourth value, if the carry-out signal designates the first value as the larger value or the third value is a fifth value, if the carry-out signal designates the second value as the larger value.
