Offline program re-mapping to improve branch prediction efficiency in embedded systems

This work presents a technique for improving the efficiency of hardware branch predictors. The key approach is to apply techniques of off-line re-mapping of the program-space in order to reduce the incidence of conflict misses in the branch hardware. This work also presents a new model for organizing temporal information between blocks in the address space, which can be applied effectively to previous re-mapping systems as well. The increased efficiency can be translated to improved performance for fixed hardware specifications, or used to reduce the hardware cost for achieving targeted performance during the design cycle.
