Sept 20 (Reuters) – Chip giant Nvidia Corp (NVDA.O) on Tuesday unveiled its new computing platform called DRIVE Thor that would centralize autonomous and assisted driving as well as other digital functions including in-car entertainment. Danny Shapiro, head of Nvidia's automotive business, said DRIVE Thor would be able to replace numerous chips and cables in the car and bring down the overall system cost, although he did not give specific numbers on savings. Some automakers have begun work on designing their own chips to gain more control and cut costs. General Motor's (GM.N) autonomous driving unit Cruise last week said it had developed its own chips to be deployed by 2025. "There's a lot of companies doing great work, doing things that will benefit mankind and we want to support them," Shapiro said.
