In an era defined by ubiquitous electronic devices and a growing emphasis on sustainability, low power Very Large Scale Integration (VLSI) design stands as a pivotal force. It is the art and science of creating integrated circuits that consume minimal energy while delivering optimal performance.

This blog post will explore ten impactful ways in which lower power VLSI design is transforming our world, from extending battery life in portable devices to reducing environmental impact across industries.

How Low Power designs are Achieved ?

Low power design is achieved by reducing the power consumption of electronic devices at all levels of abstraction, from system architecture to circuit design.

System-level design techniques include:

  • Power gating: Power gating is a technique that turns off unused parts of the chip when they are not needed. This can significantly reduce power consumption.
  • Dynamic voltage and frequency scaling (DVFS): DVFS allows the chip to operate at a lower voltage and frequency when it is not under heavy load. This can also significantly reduce power consumption.
  • Idle state management: Idle state management techniques ensure that the chip enters a low-power state when it is idle. This can help to reduce power consumption when the chip is not being used.

Architecture-level design techniques include:

  • Algorithm selection: Selecting algorithms that are more efficient in terms of power consumption can significantly reduce the power requirements of the chip.
  • Data compression: Data compression can reduce the amount of data that needs to be processed, which can lead to lower power consumption.
  • Memory hierarchy optimization: Optimizing the memory hierarchy can reduce the number of accesses to the main memory, which can lead to lower power consumption.

Circuit-level design techniques include:

  • Low-power transistors: Low-power transistors consume less power than traditional transistors.
  • Clock gating: Clock gating is a technique that prevents unused clock signals from driving transistors. This can significantly reduce power consumption.
  • Power management unit (PMU): A PMU is a hardware block that monitors the power consumption of the chip and helps to manage the power states of the chip.

Process technology techniques include:

  • Smaller transistors: Smaller transistors consume less power than larger transistors.
  • Improved process technologies: Newer process technologies can help to reduce power consumption by improving the efficiency of transistors and other components.

By applying a combination of these techniques, low power designers can significantly reduce the power consumption of electronic devices. This can lead to longer battery life, smaller and lighter devices, and reduced environmental impact.
