Abstract
Methods and apparatuses are provided for increased efficiency in a processor via control word prediction. The apparatus comprises an operational unit capable of determining whether an instruction will change a first control word to a second control word for processing dependent instructions. Execution units process the dependent instructions using a predicted control word and compare the second control word to the predicted control word. A scheduling unit causes the execution units to reprocess the dependent instructions when the predicted control word does not match the second control word. The method comprises determining that an instruction will change a first control word to a second control word and processing the dependent instructions using a predicted control word. The second control word is compared to the predicted control word and the dependent instructions are reprocessed using the second control word when the predicted control word does not match the second control word.
