AVSBus Master
Design IP
Overview

SmartDV’s AVSBus Master IP is a silicon-proven solution designed to enable efficient, high-speed communication between power management controllers and voltage regulators in advanced SoC designs. Fully compliant with the PMBus specification and AVSBus protocol, it plays a key role in dynamic voltage and frequency scaling (DVFS), helping to optimize power consumption and system performance in real time.

Designed for flexibility, the IP core is highly configurable to meet specific design requirements, supporting both ASIC and FPGA implementations while optimizing for area, power, and performance. Its compact footprint and robust feature set make it ideal for a wide range of power-sensitive applications, including mobile, automotive, and high-performance computing systems.
