A lot of fine-tuning has been done on Dhanush in the way data is processed and power is fed, which also helps achieve power savings, Kanigicherla said. The MIPS CPU has also been modified by Ineda and adapted to fit into wearable devices.
The wearable market is expected to take off in the coming years. In a study last week, Technalysis Research projected wearable device shipments to hit about 9.9 million units this year, growing to 70.5 million units by 2018. The estimate includes devices worn on the head, wrist, ears, legs and hands.
But Dhanush has competition. Qualcomm's Toq and Samsung's Gear smartwatches are based on ARM processors, and Intel is also developing Quark processors for wearable devices. Chinese company Ingenic last week shipped an integrated board called Newton for wearables with a MIPS-based CPU.
