Abstract—This project details the Verilog implementation of the Advanced Peripheral Bus (APB) protocol, focusing on a configuration with one master and multiple slaves. As part of the Advanced Microcontroller Bus Architecture (AMBA), the APB protocol plays a crucial role in facilitating communication between a master, such as a microcontroller, and various peripheral devices (slaves) within System-on-Chip (SoC) designs. The design, created using Verilog—a prominent hardware description language—follows industry standards with an emphasis on modularity and scalability. Key aspects of the APB protocol are incorporated, such as its single-master, multi-slave setup, data transfer processes, addressing schemes, and control signals. The project prioritizes design efficiency and performance optimization while maintaining full adherence to APB specifications. Special attention is given to handling bus contention, managing timing constraints, and resolving arbitration to ensure smooth communication in a variety of SoC applications.
