Learn about the Advanced Peripheral Bus (APB) protocol, a standard interface for connecting peripheral devices to a processor. This document covers the signal descriptions, transfers, operating states, error detection, and protection features of APB.
The AMBA 2 APB Specification is detailed in AMBA Specification Rev 2 (ARM IHI 0011A). This specification defines the interface signals, the basic read and write transfers, and the two APB components the APB bridge and the APB slave. This version of the specification is referred to as APB2.

1.1 About the AMBA 3 APB The APB is part of the AMBA 3 protocol family. It provides a low-cost interface that is optimized for minimal power consumption and reduced interface complexity. The APB interfaces to any peripherals that are low-bandwidth and do not require the high performance of a pipelined bus interface. The APB has unpipelined ...

AMBA is an open-standard that outlines how to connect and manage the different components or blocks within an SoC. The AMBA specification was developed by ARM and has become the de facto standard for interfacing components in an SoC. While AMBA is currently on its 5threvision and has evolved significantly over time, legacy implementations are widel...
In Revision 2.0 three distinct buses are described for facilitating on-chip communications. These are the Advanced High-Performance Bus (AHB), the Advanced System Bus (ASB), and the Advanced Peripheral Bus (APB). The AHB is the backbone of the system and is designed specifically for high performance, high-frequency components. This includes the con...
Figure 5 below shows an example AMBA system running with two AHB masters, an AHB slave, and two APB slaves. Notice the AHB arbiter, AHB decoder, and APB bridge, as well. The APB bridge has an AHB slave interface, so it looks like another slave to the masters. This system has been simplified with some signals and minor elements (such as reset signal...
Eventually, the AHB hit performance limits and by 2003 ARM had released a new generation of AMBA protocols. AMBA revision 3.0 introduced the AXI protocol. AXI stands for Advanced eXtensible Interface and offers even higher performance than the AHB, implemented through a point-to-point connection scheme. Instead of a system bus, the AXI interconnect...
In this article, we introduced the Advanced Microcontroller Bus Architecture or AMBA. AMBA is an open standard that outlines how components on an SoC can exchange data in a fast and efficient manner. AMBA has become a de facto standard and is currently on its 5th revision. Starting with revision 2.0, we looked at the AHB, ASB, and APB and how they ...
Learn about the Advanced Microcontroller Bus Architecture (AMBA), an open standard for SoC designs. APB is a simplified interface for low-frequency peripherals that connects to the AHB or ASB via an APB bridge.
AMBA was introduced by Arm in 1996. The first AMBA buses were the Advanced System Bus (ASB) and the Advanced Peripheral Bus (APB). In its second version, AMBA 2 in 1999, Arm added AMBA High-performance Bus (AHB) that is a single clock-edge protocol.
