CODE DETERMINATION USING HALF-ADDER BASED OPERAND COMPARATOR |
摘要 |
Disclosed is a method and apparatus for predicting the condition code of a condition-code-setting instruction by comparing operands in a data processing system. An operand comparator includes one or more half-adders to predict carry outs at an early time. The comparator is used in a data processing system which is operative in response to instructions having operation codes for specifying operations to be executed. The instructions also have operand fields for identifying operands to be utilized in connection with executing the instructions. |
