ABSTRACT:
The detection and selection of the appropriate branch target address in a branch history table in super scalar microprocessor is simplified by reducing the complexity of the branch history table selection logic and providing a structure which is extendible to larger instruction fetch block sizes. This is accomplished by introducing a branch pattern field into the branch history table entry which indicates the presence of other branches (branches not defined by the current entry) within the instruction fetch block.
