ARM公司提出的总线协议AHB和APB的中文资料，可作为参考资料-ARM s proposed AHB and APB bus protocol of the Chinese data, can be used as reference

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

AHB 总线规范是 AMBA 总线规范的一部分。AMBA 总线规范是 ARM 公司提出的总 线规范，被大多数 SoC 设计采用，它规定了 AHB（Advanced High-performance Bus）ASB （Advanced System Bus）APB(Advanced Peripheral Bus)。AHB 用于高性能、高时钟频率的 系统结构，典型的应用如 ARM 核与系统内部的高速 RAM，Nand Flash，DMA，Bridge 的 链接。APB 用于连接外部设
