本文讨论了一种基于ARM的RISC架构创新，称为Thumb。手机、磁盘驱动器和调制解调器等高端嵌入式控制应用对其控制器提出了更高的性能要求，同时仍需要较低的成本。通过实现第二个“压缩”指令集，Thumb减少了RISC代码大小，从而以8/16位系统成本提供了32位ARM RISC性能和功耗。
This article discusses a RISC architectural innovation from ARM known as Thumb. High-end embedded control applications such as cellphones, disk drives and modems are demanding more performance from their controllers while still requiring low cost. By implementing a second "compressed" instruction set, Thumb reduces RISC code size and so provides 32-bit ARM RISC performance and power consumption at 8/16-bit system cost.
