f Trends in Multicore Processors

Moore’s law has fueled a dramatic evolution in microprocessor and will keep doing it in forthcoming generations. Microprocessor designers have leveraged the improvements in process technology to enhance the microarchitecture of processors in different manners. In this quest for delivering higher performance, the whole industry has recently started a journey in the land of multicores. Multicores are very effective to increase computing density, by increasing the number of processing units generation after generation. The scalability of multicore processors faces multiple challenges that will require significant innovation in applications, programming paradigms and tools, and architectures. In this talk, I will describe some of the research avenues that are being pursued to address these challenges.
