Abstract :
We introduce an ultra-low-power digital signal processor (DSP) solution for wearable applications with high performance. It employs three-issue VLIW architecture with the major low-power techniques and implemented with 95K gates in Samsung 28LPP process and runs up to 200MHz. The experimental results demonstrate that a voice trigger application can operate at 6.1MHz under 0.15mW power consumption.
