Abstract
A device and method may fetch an instruction or micro-operation for execution. An indication may be made as to whether the instruction is dependent upon any source values corresponding to a set of previously fetched instructions. A value may be stored corresponding to each source value from which the first instruction depends. An indication may be made for each of the set of sources of the instruction, whether the source depends on a previously loaded value or source, where indicating may include storing a value corresponding to the indication. The instruction may be executed after the stored values associated with the instruction indicate the dependencies are satisfied.
