COPENHAGEN, Oct. 14 (Xinhua) -- The Technical University of Denmark (DTU) has developed a new self-repairing computer CPU, which is being tested by the U.S. National Aeronautics and Space Administration (NASA).

Human's abilities to repair itself and the regeneration process were an inspiration for the research team to create this platform, which is able to repair itself without human intervention, said Jan Madsen, professor from DTU and the leader of the team.

Now, this new technology has been named "electronic DNA" or "eDNA."

"We invented this computer which does not require a central CPU. Instead, there is a network of smaller CPU's cells. These cells receive an 'eDNA-frequency', which tells them what function they need to perform. If one of these cells 'dies', another cell takes over the task," Madsen said.

This means that the computer is essentially unable to repair real physical damage. Instead the damage is negated through an intelligent use of spare resources, which transfer delayed tasks to other parts of the network.

Madsen said that the system was more stable than traditional computers, as the entire system was not depending on one single CPU.

He added, "eDNA will be far more reliable and stable and is therefore particularly suited for tasks, where failure in a system can prove disastrous, such as space travel."

According to Danish daily Berlingske Tidende, NASA has shown great interest in the project, as some of its technologies can be used to ensure a high-tech equipment not breaking down in the middle of a mission.

Currently, the project has entered the testing phase at NASA's Jet Propulsion Laboratory. According to the plan, test results will be released in November.
