Computer scientists at North Carolina State University have claimed that a new hardware developed by them increases the communication speed among the cores on a multi-core computer chip.

For faster performance, multiple cores on a single chip must communicate with each other. But, at present, there are no direct ways for cores to communicate.

NC State University assistant professor Dr James Tuck said the technology, called HAQu, is more efficient than the best software available because it provides a single instruction to send data to another core.

Tuck said the technology is also more energy efficient. He said, "It actually consumes more power when operating but, because it runs so much more quickly, the overall energy consumption of the chip actually decreases."

The research paper is co-authored by Tuck, students Sanghoon Lee and Devesh Tiwari, and Dr Yan Solihin, an associate professor of electrical and computer engineering at the university.
