Concurrencies in instructions and data movement must be totally specified at compile time however scheduling of branch instructions at compile time is very hard. To handle branch instructions trace scheduling is accepted. Trace scheduling is derived from the prediction of branch decisions with a little reliability at compile time. Prediction is derived from some heuristics hints given by programmer or using profiles of a number of previous program executions.
