Semiconductor designer Arm plans to axe up to 15 percent of staff, it said Tuesday, after Japanese owner SoftBank failed to offload the subsidiary to US chip giant Nvidia.

Arm, located in the English university city of Cambridge, said the proposed cuts from a global workforce of more than 6,000 comes after Nvidia last month scrapped a blockbuster $40-billion takeover following regulatory objections.

Founded in 1990, Arm specialises in microprocessors and dominates the global smartphone market.

Its technology was present in Apple's first iPhone released in 2007.

Arm chips are present also in sensors, smart devices and .
