Qualcomm beefed up its automotive processor business on Monday by agreeing to acquire vehicle-to-everything chip outfit Autotalks. Its technology fits into a field that Qualcomm has long championed — crash safety protections. Qualcomm provides Snapdragon connectivity, infotainment, digital dashboard, digital chassis and autonomy technologies to automakers in a low-energy package that is important for electric vehicles. Revenue for Qualcomm’s automotive arm increased 44.5 percent to $1.4 billion during its most recent fiscal year, which ended in September. Hagai Zyss, chief executive of Autotalks, said the acquisition aims to accelerate the adoption of vehicle-to-everything technology.
