Abstract
The method and system of the present invention permits enhanced instruction dispatch efficiency in a superscalar processor system capable of fetching an application specified ordered sequence of scalar instructions and simultaneously dispatching a group of the scalar instructions to a plurality of execution units on a nonsequential opportunistic basis. A group of scalar instructions fetched in an application specified ordered sequence on a nonsequential opportunistic basis is processed in the present invention. The present invention detects conditions requiring serialization during the processing. In response to a detection of a condition requiring serialization, processing of particular scalar instructions from the group of scalar instructions are selectively controlled, wherein at least a portion of the scalar instructions within the group of scalar instructions are thereafter processed in a serial fashion.
