Abstract

Methods and apparatus for managing stack data in multi-core processors having scratchpad memory or limited local memory. In one embodiment, stack data management calls are inserted into software in accordance with an integer linear programming formulation and a smart stack data management heuristic. In another embodiment, stack management and pointer management functions are inserted before and after function calls and pointer references, respectively. The calls may be inserted in an automated fashion by a compiler utilizing an optimized stack data management runtime library.
