Abstract-Continuous effort to achieve higher performance without driving up the power consumption and thermal effects has led the researchers to look for alternative architectures for microprocessors. Like the parallel processing which is extensively used in today's all microprocessors, multicore architecture which combines several independent microprocessor cores in a single die has currently become very popular in most high performance intergraded circuits. Although multi-core processor offers excellent instruction execution speed with reduced power consumption, optimizing performance of individual processors and then incorporating them by interconnection on a single chip is a non-trivial task. This paper investigates the leading challenges associated with current high performance multi-core processor in terms of interfacing different cores, design automation and verification, software adaptability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
