The Advanced Microcontroller Bus Architecture (AMBA) Advanced Peripheral Bus (APB), developed by Arm, is a
simple, low-power, and low-complexity bus protocol designed for efficient communication between processors and
low-bandwidth peripheral devices. This project presents the Register Transfer Level (RTL) implementation of the APB
protocol to enable reliable data transfer between a master and multiple peripheral slave devices. The proposed design
consists of APB master, slave, and decoder modules that support both read and write operations using a two-phase
transfer mechanism comprising the setup and enable phases. The RTL architecture is implemented using Verilog
Hardware Description Language (HDL) to achieve synchronous operation, low power consumption, and minimal
hardware complexity. Functional verification is performed through simulation to validate address decoding, control
signal generation, and data transfer operations. The simulation results confirm the correct functionality of the APB
protocol, ensuring efficient communication between the master and peripheral devices with simplified timing
requirements. The implemented system provides a scalable, reliable, and cost-effective solution for integrating low
speed peripherals in embedded systems and System-on-Chip (SoC) applications.
