［译注 2］：Jazelle 是 ARM 处理器的硬件 Java 加速器。
［译注 3］：MMU，存储器管理单元，用于实现虚拟内存和内存的分区保护，这是应用处理器与嵌入式处理器的分水岭。电脑和数码产品所使用的处理器几乎清一色地都带 MMU。但是 MMU 也引入了不确定性，这有时是嵌入式领域——尤其是实时系统不可接受的。然而对于安全关键（safety-critical）的嵌入式系统，还是不能没有内存的分区保护的。为解决矛盾，于是就有了 MPU。可以把 MPU 认为是 MMU 的功能子集，它只支持分区保护，不支持具有 “定位决定性” 的虚拟内存机制。
到了架构 7 时代，ARM 改革了一度使用的，冗长的、需要 “解码” 的数字命名法，转到另一种看起来比较整齐的命名法。比如，ARMv7 的三个款式都以 Cortex 作为主名。这不仅更加澄清并且 “精装” 了所使用的 ARM 架构，也避免了新手对架构号和系列号的混淆。例如，ARM7TDMI 并不是一款 ARMv7 的产品，而是辉煌起点——v4T 架构的产品。
