ABSTRACT:
A method of efficient code generation for modulo scheduled uncounted loops includes: assigning a given stage predicate to each instruction in each stage, including assigning a given stage predicate to each instruction in each speculative stage; and using the stage predicate to conditionally enable or disable the execution of an instruction during the prologue and epilogue execution.
