Embedded appliances such as high-end cell phones require not only high performance but also a performance guarantee. The authors demonstrate a performance guarantee framework using an asymmetric multiprocessing approach. They implemented the proposed method on a multicore processor using Linux. Evaluation results show that the method improves the performance guarantee while maintaining software compatibility.
