Scheduler for use in a microprocessor that supports data-speculative execution |
摘要 |
A microprocessor may include several execution units and a scheduler coupled to issue operations to at least one of the execution units. The scheduler may include several entries. A first entry may be allocated to a first operation. The first entry includes a source status indication for each of the first operation's operands. Each source status indication indicates whether a value of a respective one of the first operation's operands is speculative. The scheduler is configured to update one of the first entry's source status indications to indicate that a value of a respective one of the first operation's operands is non-speculative in response to receiving an indication that a value of a result of a second operation is non-speculative.
