New features and enhancements: Signal width properties, Write strobes, User signaling update, Signal validity rules, and interface protection using parity. Regularized terminology to be Manager and Subordinate.

一、AHB和APB到底是什么. AHB(Advanced High-performance Bus), 高速总线，用来接高速外设的。APB (Advanced Peripheral Bus) 低速总线，用来接低速外设的。 一般的接法如上。高速的接在AHB上，低速的接在APB上。中间有一个AHB2APB的桥。你可以理解这个桥也是一个告诉 …

The AMBA Advanced High-performance Bus (AHB) specification defines an interface protocol most widely used with Cortex-M processors, for embedded designs and other low latency SoCs. The AHB5 protocol builds upon the previous generation of AHB-Lite with two key goals:

AMBA (Advanced Microcontroller Bus Architecture) 高级微处理器总线架构. 定义了高性能嵌入式微控制器的通信标准，可以将RISC处理器（精简指令集处理器）集成在其他IP芯核和外设中，它是有效连接IP核的“数字胶”，并且是ARM复用策略的重要组件；它不是芯片与外设之间的接口，而是ARM内核与芯片上其他元件进行通信的接口。 比如Xilinx公司的 Zynq芯片，就是ARM与 FPGA 之间的连接通路 .主要包括： AHB (Advanced High-performance Bus) 高级高性能总线. ASB …

The ARM AMBA 5 AHB Protocol Specification provides detailed information on secure/non-secure signaling, extended memory types, exclusive transfers, and other advanced features.

AHB Bus Matrix，即总线矩阵，其实际上就是一个互连（Interconnect）。用于连接满足该总线协议的外设，包括Master和Slave。基于该模块，我们可以快速的完成“连连看”工作。将设计好的IP封装成AHB协议，然后挂载上去即可。这样就完成了简单的SoC集成工作。

ATB is a data-agnostic interface for transferring trace information between components in a trace system. The trace components and bus sit in parallel with the peripherals and interconnect, and provide visibility for debug purposes. The AMBA 4 APB specification introduces transaction protection and sparse data transfer to the APB interface.

AMBA® 3 AHB-Lite 协议，中文版。AMBA AHB-Lite是面向高性能的可综合设计，提供了一个总线接口来支持Master并提供高操作带宽。最普通的AHB-Lite从器件是内存器件，外部存储器接口和高带宽外围器件。

Multi-layer AHB is an interconnection scheme, based on the AHB protocol, that enables parallel access paths between multiple masters and slaves in a system. This is achieved by using a more complex interconnection matrix. Key advantages are: You can develop multi-master systems with an increased available bus bandwidth.

2025年2月1日 · 在ARM AHB总线协议中，有以下几个关键概念和技术要点： 1. **总线主设备（Bus Master）**：总线上的每个组件可能成为主设备，发起数据传输请求。例如，CPU或DMA（Direct Memory Access）控制器可以作为主设备向内存...
