Condition code register architecture for supporting multiple execution units |
摘要 |
A condition code register architecture for supporting multiple execution units is disclosed. A master execution unit is coupled a master condition code register such that condition codes generated by the master execution unit are stored in the master condition code register. A non-master execution unit is coupled to a shadow condition code register such that condition codes generated by the non-master execution unit are stored in the shadow condition code register. A tag unit coupled to the master execution unit and the non-master execution unit such that an entry within the master condition code register can be read only when a corresponding entry within the tag unit is referenced to the master execution unit or the master condition code register.
