The last decade has seen a faster accretion of wearable and implantable devices like action cameras, health tracking bands, smart
watches, and pacemakers. Contradictory to traditional computing platforms, the above mentioned devices squander important
amounts of time reading sensors like microphones, image sensors, accelerometers, electrocardiogram (ECG) sensors, etc., and
operating the detected data (Fig. 1). Frequent or continuous sensing poses a replacement challenge to energy potency as a result of
information transfer from off-chip sensors consumes momentous energy. Disparate to on-chip buses that have benefited from
enhancements in semiconductor development technology, off-chip buses, and especially serial interfaces that are normally used with
sensors (e.g., Serial Peripheral Interface (SPI), InterIntegrated Circuit (I2C), MIPI Camera Serial Interface (CSI)), have improved
far more slowly. As a result, up to thirteen percent of energy dissipation in such systems will be attributed to information.
