“…Normalized values facilitate the comparison of various microcontroller architectures by showing the energy expenditure for each operation or instruction, regardless of the time taken. Authors in [20] propose the usage of a clock-frequency switching technique that can reduce the energy consumption of microcontroller-based sensor nodes. The concept of reducing energy consumption is based on switching the operating clock between low and high frequencies, depending on the application codes of the microcontroller unit (MCU).…”

Dynamic voltage and frequency scaling (DVFS) is a technique used to optimize energy consumption in ultra-low-power embedded systems. To ensure sufficient computational capacity, the system must scale up its performance settings. The objective is to conserve energy in times of reduced computational demand and/or when battery power is used. Fast Fourier Transform (FFT), Cyclic Redundancy Check 32 (CRC32), Secure Hash Algorithm 256 (SHA256), and Message-Digest Algorithm 5 (MD5) are focused functions that demand computational power to achieve energy-efficient performance. Selected operations are analyzed from the energy consumption perspective. In this manner, the energy required to perform a specific function is observed, thereby mitigating the influence of the instruction set or system architecture. For stable operating voltage scaling, an exponential model for voltage calculation is presented. Statistical significance tests are conducted to validate and support the findings. Results show that the proposed optimization technique reduces energy consumption for ultra-low-power applications from 27.74% to up to 47.74%.

“…where η = πf A 2c 2 is a dimensionless parameter useful for quantifying the relativistic contribution to the measurement. Let δ be the smallest time difference that we can measure through a measurement system (clock cycle of a CPU [10] or MCU [4], oscillation of a quartz using piezoelectricity [1]) and ∆ be the duration of the experiment. Then, ∆ = δ τ 0 ∆τ .…”

Embedded systems are rapidly being used in clinical and biological applications, as well as commercial, telecommunications, government, and other business applications. Embedded system solutions are growing in popularity, not only with types of technologies, garments, industries, healthcare and military hardware, and mobile computers, but with software solutions like' electronic worlds' and 'mobile worlds,' deep learning, and internet of things, which allow for the creation of a wide range of application. With the growth of viral illnesses like the Covid-19 virus, tele-health technologies for diagnostics, prognostic, and patient treatment have become more important in recent decades. In medical technologies, embedded device techniques have taken a significant role. Developing techniques to improve the security of medical practitioners in the case of pandemic contagious diseases, such as epidemics, is particularly important. Patients released from clinics home-based or in treatment wards that are non-intensive during the quarantine period, or segregated in their residences, outpatients’ departments, and moderately ailing individuals are progressively being monitored remotely, instantaneously, safely, and rapidly for this reason. The applications biomedical applications in embedded systems will be discussed in this paper.
