Static Voltage Scaling
Static Voltage Scaling (SVS) is a power management technique in digital circuit design that involves setting a fixed, reduced supply voltage for a processor or integrated circuit to lower power consumption. It operates by statically adjusting the voltage based on worst-case performance requirements or predefined operating modes, without dynamic changes during runtime. This approach is commonly used in embedded systems and low-power devices to extend battery life while meeting computational needs.
Developers should learn Static Voltage Scaling when designing energy-efficient systems, such as IoT devices, wearables, or battery-powered embedded applications, where minimizing power usage is critical. It is particularly useful in scenarios with predictable workloads or fixed performance targets, as it allows for simple implementation compared to dynamic voltage scaling, reducing hardware complexity and cost. However, it may not be suitable for applications with highly variable computational demands, as it lacks runtime adaptability.
