从ARM ArchitectureReference ManualARMv7-A and ARM®v7-R edition摘录如下：
The following architecture variants are now obsolete:
ARMv1, ARMv2, ARMv2a, ARMv3, ARMv3G, ARMv3M, ARMv4xM, ARMv4TxM, ARMv5,
ARMv5xM, ARMv5TxM, and ARMv5TExP.
The valid variants of ARMv4, ARMv5, and ARMv6 are as follows:
ARMv4 The earliest architecture variant covered by this manual. It includes only the ARM
instruction set.
ARMv4T Adds the Thumb instruction set.
ARMv5T Improves interworking of ARM and Thumb instructions. Adds count leading zeros (CLZ)
and software breakpoint (BKPT) instructions.
ARMv5TE Enhances arithmetic support for digital signal processing (DSP) algorithms. Adds preload
data (PLD), dual word load (LDRD), store (STRD), and 64-bit coprocessor register transfers
(MCRR, MRRC).
ARMv5TEJ Adds the BXJ instruction and other support for the Jazelle® architecture extension.
ARMv6 Adds many new instructions to the ARM instruction set. Formalizes and revises the memory
model and the Debug architecture.
ARMv6K Adds instructions to support multi-processing to the ARM instruction set, and some extra
memory model features.
追问能列举几个ARM3处理器架构的CPU型号吗？现在比较常用的。
追答目前常用的ARM7TDMI 是V4的，V3的都没见过。
