RTL Implementation of AMBA AHB Protocol using Verilog

Abstract

Abstract: The enactment of a computer system heavily depends on the design of its bus interconnect. A poorly designed system bus can hinder the transmission of instructions and data between the processor and memory or between peripheral devices and memory. To address these challenges, the Advanced Microcontroller Bus Architecture (AMBA) provides an open standard for connecting and managing functional blocks in a System-on-Chip (SoC). This architecture allows for developing multi-processor designs with many controllers and peripherals while ensuring the system is designed correctly the first time. Furthermore, the AMBA specifications are royalty-free and platform-independent. They can be used with any processor architecture. The project will provide an RTL view and an extracted design summary of the AMBA AHB module at the system-on-chip level. The AMBA High-performance Bus (AHB) is another part of the AMBA family of conventions. The AHB is designed to support highperformance, high-clock system modules and serves as the system's high-performance backbone bus. The AHB enables the efficient connection of low-power peripheral functions to processors, on-chip memories, and external off-chip memory interfaces. All signal transitions in the AHB relate only to the rising clock edge, allowing AHB peripherals to be easily integrated into any design flow. The project also describes the AMBA AHB design and implementation using Verilog, with read/write operations implemented using the Xilinx simulator.
