scientist inChinahave built a new type of tensor processing unit ( TPU ) — a special type of data processor chip — usingcarbon nanotubesinstead of a traditional silicon semiconductor . They say the new chip could give the room access to more energy - efficientartificial intelligence(AI ) .
AI framework are enormously datum - intensive and require massive sum of money of computational power to run . This presents a significant obstacle to training and scale up automobile learning models , peculiarly as the demand for AI applications develop . This is why scientist are working on making young components — from processor tocomputing memory — that are project to consume rescript of magnitude less vigour while running the necessary computations .
Unlike conventional TPUs, this new chip is the first to use carbon nanotubes — tiny, cylindrical structures made of carbon atoms arranged in a hexagonal pattern — in place of traditional semiconductor materials like silicon.
Google scientists create the TPUin 2015 to address this challenge . These specialized chips act as consecrate hardware particle accelerator for tensor operations — complex mathematical computation used to train and run AI models . By offloading these tasks from the central processing unit ( CPU ) and art processing unit ( GPU ) , TPUs enable AI models to be trained faster and more expeditiously .
Unlike conventional TPUs , however , this new scrap is the first to use carbon nanotubes — midget , cylindrical structures made of carbon copy atoms arranged in a hexangular pattern — in place of traditional semiconductor materials like silicon . This structure allows electrons ( charged particles ) to flow through them with minimal underground , making carbon nanotubes fantabulous conductors of electricity . The scientists published their inquiry on July 22 in the journalNature Electronics .

According to the scientists , their TPU wipe out just 295 microwatts ( μW ) of top executive ( where 1 W is 1,000,000 μW ) and can deliver 1 trillion trading operations per watt — a building block of energy efficiency .
" From ChatGPT to Sora , artificial news is ushering in a fresh revolution , but traditional Si - based semiconductor technology is increasingly ineffective to fulfill the processing need of massive amounts of data,“Zhiyong Zhang , co - author of the report and professor of electronics at Beijing ’s Peking University , toldTechXplore . " We have find a solution in the brass of this global challenge . "
The new TPU is draw up of 3,000 carbon carbon nanotube transistors and is built with a systolic array architecture — a web of processors put in a gridiron - alike pattern .

Systolic array draw datum through each central processing unit in a synchronise , tone - by - step sequence , standardised to item moving along a conveyer belt belt . This enables the TPU to do multiple computation simultaneously by coordinating the flow of data and ensuring that each processor form on a pocket-sized part of the task at the same meter .
This parallel processing enable computations to be performed much more quickly , which is crucial for AI models processing large quantity of data . It also reduces how often the remembering — specifically a type call static random - entree retentiveness ( SRAM ) — needs to take and write data , Zhang said . By downplay these operations , the Modern TPU can perform computation faster while using much less vigour .
To prove their newfangled chip , the scientists build a five - stratum neural internet — a appeal of machine learning algorithms design to mimic the structure of the human brain — and used it for image acknowledgment tasks .
The TPU achieve an accuracy pace of 88 % while maintain power use of only 295 μW. In the hereafter , similar atomic number 6 nanotube - based engineering science could provide a more zip - effective choice to silicon - based chip , the researchers tell .
The scientist plan to carry on refining the chip to ameliorate its performance and make it more scalable , they said , include by exploring how the TPU could be integrated into Si CPUs .
