Abstract
A method for re-triggering wakeup to handle time skew between a scalar operation and a vector operation is provided. The method includes: initiating, before a Load-Store (LST) pipeline completes an execution of a load operation corresponding to a vector micro-operation (uop) dispatched to a baler issue queue, a respective load operation in a Load (LD) pipeline corresponding to the vector uop; triggering a speculative wakeup from the LD pipeline during an execution of the respective load operation; triggering a second wakeup corresponding to the speculative wakeup from the LD pipeline; and waking up, based on the second wakeup, the vector micro-operation in the baler issue queue of the baler unit.
