【特斯拉正在自主研发无人驾驶汽车的AI芯片】特斯拉首席执行官埃隆·马斯克称,该公司为自动驾驶打造的定制化芯片几乎准备就绪。此前特斯拉一直使用英伟达的Drive平台,转换为自主研发的发展战略是由于希望通过自主设计满足对效率的要求。此前公司使用英伟达硬件时,计算机视觉软件的效率是每秒200帧。但有了自主研发的芯片之后,效率将能提高到每秒2000帧。

 

Tesla is quietly making its own AI chip for self-driving cars

New Autopilot hardware will swap NVIDIA GPUs with in-house replacements.

In a recent earnings call, Tesla CEO Elon Musk revealed the automaker has been 'stealth' developing a custom-built AI chip for at least two years.

The self-driving technology is to be used in Tesla's Model 3Model X and Model S Autopilot systems, and according to Musk, it will give its autonomous cars additional processing power. Tesla Director Pete Bannon explained the new chip -- which will be incorporated in a third update for Tesla's Autopilot hardware -- is currently undergoing road tests. Unlike previous Autopilot versions which relied on NVIDIA GPUs, the upgraded hardware will reportedly process a lofty 2,000 frames per second -- a significant rise from 200.

Tesla has long entertained the possibility of manufacturing in-house AI chips for its autonomous EVs. Reports last year indicated the company would collaborate with AMD-spawned GlobalFoundries to kickstart production, but a spokesperson quickly denied the partnership. That didn't put Tesla's plan to release self-driving cars by 2019 on ice though -- CEO Elon Musk claimed it was in the process of "developing specialized AI hardware" just three months later.

This week, Tesla reported a record loss of $718 million, a side-effect of ramping up production on the Model 3. Musk reassured shareholders that consumer demand was still healthy and that Tesla would emerge profitablein the second half of 2018. Adding classic Atari games to its Model 3 could score the company a much-needed competitive edge.
