MIT's 110-core Execution Migration CPU chip moves instructions to the data

A 110-core CPU chip has been developed by computer scientists at the Massachusetts Institute of Technology. The chip is based on a new architecture in which instead of bringing data across the chip to the core that happens to want it, you move the program to the core where the data is stored. In practice, this new architecture reduces the amount of on-chip data exchange tenfold, along with the heat and infrastructure demanded by conventional chip architecture. Read More

Stanford scientists build first carbon nanotube computer

In a technological tour de force, researchers at Stanford University have constructed a one-bit, one-instruction programmable computer on a chip using carbon nanotube-based electronics for all logic elements. Containing 178 carbon nanotube field-effect transistors, the computer is only able to carry out only one instruction, called SUBNEG. However, SUBNEG is Turing-complete, allowing the computer to run, albeit with an extraordinary level of inefficiency, any program, given enough memory, time, and programming ingenuity. Read More
