Abstract

This project introduces a groundbreaking approach to address the challenge of periodic signal compression. By proposing a novel adaptive coding method, coupled with hardware-assisted data compression, we have developed a new architecture model tailored for efficient data compression. The selected compression scheme has demonstrated remarkable results, showcasing reduced memory communication volume and power consumption in the cache memory path of benchmark systems. With a reduction range of 4.2% to 35.2%, this innovation paves the way for affordable smart sensing, monitoring, diagnostics, and protection in emerging low-cost device types. Consequently, this cutting-edge technology enhances electrical signal compression and contributes to grid improvement. Additionally, we explore the novel application of harnessing wasted thermal energy in the Read-Only Memory (ROM) using thermoelectricity (TE). This approach captures the excess thermal energy, converting it into electrical energy through optimized supercapacitor charging, resulting in efficient energy utilization. This innovation intersects the fields of embedded systems, data compression, energy efficiency, and smart grid technology.
