Wrist watch GPS running monitors operate for up to 30 hours

The processor can be customised to handle both DSP and embedded control processing functions. By integrating control and signal processing in a single core, the automated Xtensa Processor Generator allows designers to create competitive, low power features. 

“Low power features are critical for chip designs in our wearables segment,” said Kenichi Ushiyama, General Manager, Epson. “By adapting the Cadence Tensilica Xtensa processor to our needs, we were able to combine the control and GPS signal processing functions into one efficient core, saving power and area for this very space-constrained design.”
