Overview of AMBA AHB2APB Bridge for SOC Interconnects

The swift evolution of technology demands a highly efficient system with seamless integration of components. Evolution of System on Chip (SOC) has modified making use of different components within a single chip. Therefore, it becomes very crucial to manage these components. The Advanced Microcontroller Bus Architecture (AMBA) bus architecture, a standard SOC interconnection, enhance Intellectual Property (IP) core reusability and streamlines data transmission. Advanced High-Performance Bus (AHB) is part of AMBA family used for High-speed data transfer communication protocol manages with high bandwidth components like processor or memory. Advanced Peripheral Bus (APB) is specifically used for connecting with low bandwidth components like keyboard and mouse. Thus, the importance of AHB2APB bridge becomes very vital. It is the backbone of all data transfer that takes place within a SOC. This paper focuses on reviewing different reported studies in this field, implementing Register Transfer Level (RTL) schematic of AHB2APB bridge.
