A method is provided for executing a plurality of parallel executable sequences of instructions on a processor having a plurality of execution units operated by a single instruction unit. The method includes a) detecting a plurality of sequences of instructions adapted for parallel execution from instructions being provided to the processor, wherein each sequence is adapted for execution by a subset of the plurality of execution units and b) storing information representing a stall status of the execution units. Then, a step c) is performed, wherein, for each unexecuted sequence of the plurality of sequences: i) all of the plurality of execution units other than the subset which corresponds to the unexecuted sequence are stalled, and ii) the sequence of instructions is executed by the corresponding subset. Thereafter, it is determined in a step d) whether a current stall status of the plurality of execution units matches the stall status represented by the stored information. When there is no match, the steps b) through d) are repeated until there is a match in which the current stall status represented by the stored information matches the stored information.
