Increasing the Energy-Efficiency of Wearables Using Low-Precision Posit Arithmetic with PHEE
Posit arithmetic in 8-16 bits achieves comparable accuracy to 16-32 bit floats in cough detection and ECG R-peak tasks, with PHEE RISC-V hardware showing 38% smaller area and 42.3% less power in 16nm synthesis.
