A wide variety of existing and emerging applications in recognition, mining and synthesis and machine-to-human interactions tolerate small errors or deviations in their computational results. Digital systems can exploit this error tolerance to increase their energy efficiency, which is crucial in high performance wearable electronics and in emerging low power systems for the internet-of-things. A...
This paper presents an energy-efficient digital signal processor (DSP) for rectangular-to-polar conversion in 802.11ad polar transmitter working on 60 GHz band. Firstly, system simulations with a complete transmission chain are conducted with regard to error vector magnitude and output spectrum, which allows to systematically optimize the design requirements on the DSP block. Secondly, algorithm and...
