For years, Li-Shiuan Peh, the Singapore Research Professor of Electrical engineering and Computer science at MIT, has argued that the massively multicore chips of the future will need to resemble little Internets,
it also solves one of the problems that has bedeviled previous attempts to design networks-on-chip:
In today chips, all the cores typically somewhere between two and six are connected by a single wire,
In a network-on-chip, each core is connected only to those immediately adjacent to it. ou can reach your neighbors really quickly,
Every core on a chip has its own cache a local, high-speed memory bank in which it stores frequently used data.
Most chips address this question with a protocol called noopy, because it involves snooping on other corescommunications.
But in a network-on-chip data is flying everywhere, and packets will frequently arrive at different cores in different sequences.
and their colleagues solve this problem by equipping their chips with a second network, which shadows the first.
During each interval, the chip 36 cores are given different, hierarchical priorities. Say, for instance, that during one interval,

These devices consist of microfluidic channels engraved on tiny chips, but current versions usually require a great deal of extra instrumentation attached to the chip,
limiting their portability. Much of that extra instrumentation is needed to keep the particles flowing single file through the center of the channel,
This could lead to chips that combine optical and electronic components in a single device, with far lower losses than when such devices are made separately and then interconnected,

#New Technique Could Enable Chips with Thousands of Cores Researchers from MIT have unveiled the first fundamentally new approach to cache coherence in more than three decades,
a memory-management scheme that could help enable chips with thousands of cores. In a modern, multicore chip, every core or processor has its own small memory cache, where it stores frequently used data.
But the chip also has shared a larger cache, which all the cores can access. If one core tries to update data in the shared cache,
other cores working on the same data need to know. So the shared cache keeps a directory
In a 64-core chip, it might be 12 percent of the shared cache. And that percentage will only increase with the core count.
Envisioned chips with 128,256, or even 1, 000 cores will need a more efficient way of maintaining cache coherence.
In a 128-core chip that means that the new technique would require only one-third as much memory as its predecessor.
But with a 256-core chip, the space savings rises to 80 percent, and with a 1, 000-core chip, 96 percent.
When multiple cores are simply reading data stored at the same location, there no problem.
With a directory system, the chip looks up which cores are working on that data and sends them messages invalidating their locally stored copies of it. irectories guarantee that
In massively multicore chips, Yu says, this could lead to performance improvements as well. e didn see performance gains from that in these experiments,
however, that chip designers are conservative by nature. lmost all mass-produced commercial systems are based based on directory protocols,
