Abstract
A group completion table (GCT) that manages the execution of instruction groups having more than one executable instruction is disclosed. The GCT includes a plurality of table entries, wherein each of the table entries is associated with a respective instruction group. Each table entry in the GCT includes a plurality of instruction completion identifiers, wherein each of the instruction completion identifiers corresponds to a specific instruction in the associated instruction group. The table entry also includes a trouble identifier that is utilized to flag the occurrence of any exception condition encountered in the execution of any instruction in the instruction group. In a related embodiment, the trouble identifier utilized in the table entry is a single bit.
