Smart sensors are electronic systems that embed a sensor and the digital logic to process the captured data in a single integrated circuit. Many applications involving these systems have real-time requirements, imposing a restriction on the time window in which each sample must be captured and processed. However, the required processing is often too computationally heavy to handle, within the time budget, using an area and power-constrained embedded CPU. One solution to this problem consists in offloading expensive operations to dedicated hardware (HW) accelerators, which can execute a (set of) specific processing tasks faster and more efficiently than a CPU. An example is digital signal processors (DSPs).
