Design of Low Power SPI Protocol using Clock Gating Techniques

This research explores the integration of clock gating techniques to enhance the performance of the Serial Peripheral Interface (SPI) protocol commonly used in embedded systems. This approach involves selectively disabling the clock signal during idle states of the blocks, resulting in significant reductions in power consumption while maintaining high-speed and reliable data transfer. Through extensive simulations and experimental validations, our study demonstrates the efficiency of the proposed clock gating strategy in achieving a balance between power consumption and communication speed. This research not only benefits SPI applications but also serves as a model for optimizing other communication protocols. The results presented in this paper offer valuable insights into implementation challenges and considerations associated with integrating clock gating into the SPI protocol, paving the way for further advancements in power-aware design methodologies.
