Abstract
Software Managed Manycore (SMM) architectures with scratch pad memory for reach core are a promising solution for scaling memory. In these architectures the code and data of the tasks mapped to the cores is explicitly managed by the compiler and often require inter-procedural information and analysis. But, a call graph of the program does not have enough information, and the Global CFG has too much information. Most new techniques informally define and use GCCFG (Global Call Control Flow Graph)—a whole program representation that succinctly captures the control-flow and function call information—to perform inter-procedural analysis. Constructing GCCFGs for several cases in common applications. The present disclosure provides unique graph transformations to formally and correctly construct GCCFGs for optimal compiler management of manycore systems.
