"Ultra-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."

The Xtensa processor can be customized to handle both performance-intensive digital signal processing (DSP) and embedded control processing functions. The patented automated Xtensa Processor Generator allows designers to create more competitive and differentiated features with the lowest power by integrating control and signal processing in a single core.
