  • Patent number: 8984475
    Abstract: Provided is an apparatus and method for generating code overlay capable of minimizing the number of memory copies. A static temporal relationship graph (STRG) is generated in which each of functions of a program corresponds to a node of the STRG and a conflict miss value corresponds to an edge of the STRG. The conflict miss value is the maximum number of possible conflict misses between functions. Overlay is generated by selecting at least one function from the STRG, calculating an allocation cost for each region of a memory to be given when the at least one selected function is allocated, and allocating the at least one selected function to a region that has the smallest allocation cost.
