The spread of the Internet of Things (IoT) and Artificial Intelligence at the Edge (Edge AI) has fundamentally redefined the design paradigms embedded systems. These systems have transformed themselves into a highly connected node out of the isolated single functional microcontrollers. Usually requiring real-time deterministic processing power, area and thermal factor requirement. This paper examines the overlap between the principles of Very-Large-Scale Integration (VLSI) design and the current embedded computing architectures. Our multi-layered, detailed analysis of hardware-level optimizations with special emphasis on. sub-micron CMOS corner analysis of Process, Voltage and Temperature (PVT) variations and the use of transmission gate (TG) logic to convert sequential elements to power-efficient versions. Implementation of 3- gating. Transmission gate (TG) logic of sequential elements. In addition, this paper explores the accelerator of Digital Signal Processing (DSP), mathematics scheduling of Operating Systems (RTOS) Real-Time, and why Universal Verification is required. Procedure (UVM) to make things work. A 47.8% higher improvement in the indicates numerical simulations at the 45nm technology node. Power-Delay Product (PDP) of custom D flip-flops, laying a strong physical groundwork for next-gen intelligent edge devices.
