Introduction

AMBA-Advanced Microcontroller Bus Architecture

Widely used as the on-chip bus for ARM processors.

Four Distinct Buses of AMBA,

• Advanced eXtensible Interface (AXI)
  
• Advanced High-performance Bus (AHB)
  
• Advanced System Bus (ASB)
  
• Advanced Peripheral Bus (APB)

AMBA-AHB Features

• High Performance
• Pipelined Operation
• Multiple Bus Master
• Split Transfer
• Burst Transfer

AMBA-ASB Features

• High Performance
• Pipelined Operation
• Multiple Bus Master

AMBA-APB Features

• Low Power
• Latched Address
• Simple Interface
• Suitable to many Peripherals
