Abstract:
A method for reducing a number of operations replayed in a processor includes decoding an operation to determine a memory address and a command in the operation. If data is not in a way predictor based on the memory address, a suppress wakeup signal is sent to an operation scheduler, and the operation scheduler suppresses waking up other operations that are dependent on the data.
