A 110-core chip has been developed by Massachusetts Institute of Technology as it looks for power-efficient ways to boost performance in mobile devices, PCs and servers. The processor, called the Execution Migraine Machine, tries to determine ways to reduce traffic inside chips, which enables faster and more power-efficient computing, said Mieszko Lis, a postgraduate student and Ph.D. candidate at MIT, during a presentation at the Hot Chips conference in California.
