Increasingly complex consumer electronics applications call for embedded processors with higher performance. Multi-cores are capable of delivering the required performance. However, many of these embedded applications must meet some form of soft real-time constraints, and program behavior on multi-cores is even harder to predict than on single-cores. In this paper, the authors highlight the greater performance variability of irregular applications (non-regular control flow and/or data structures) across data sets when parallelized and run on a multi-core.
